GSW: 1972 MEETING MINUTES

 

Geological Society of Washington

January 12, 1972

The 953rd meeting of the Society was called to order at 8:03 P.M. by 2nd Vice-President Lynn Hoover in the absence of the more senior members of the newly instated hierarchy, President Stewart and 1st Vice-President Roedder.  Hoover announced the availability of the preliminary meeting announcement for the first annual meeting of the Eastern Section of the A.A.P.G., to be held in Columbus, Ohio, May 24th to 27th, 1972.

L.G. Henbest gave a silent informal communication consisting of Webster's definition of Kenyte - "An alkali-trachyte with phenocrysts of anorthoclase and aegerite in a trachytic to hyalophyllitic groundmass of alkali-feldspar laths and grains of pyroxene and amphibole rich in soda, and usually some glass.  In some varieties, olivine is present." Henbest asked, silently, for "one on the rocks, with olivine, please.  Easy on the glass!" The secretary used the "informal plea" in asking that discussants of talks identify themselves by name, knowing full well in advance that the informal plea, carrying very little weight, would be totally ignored.  To a man, it was.  The minutes of the preceding meet­ing were read, and approved fortunately as they had been securely glued forever in the minutes book.

The first speaker of the regular program was W.G. Leo, who described the "U.S. Geological Survey Program in Turkey, 1968-1970", a cooperative venture with the M.T.A., Turkish equivalent of both the U.S. Geological Survey and Bureau of Mines.  A brief summary of the geology of Turkey was followed by discussion of the various objectives of the program includ­ing base metal exploration, particularly for iron, aeromagnetic surveying, diamond core drilling and acquisition of equipment.  The need for equipment was made obvious by the statement that the horses and mules of the area were considerably more valuable than the geologists and were not let out of the sight of their owners.  The paper was questioned by Stancioff twice, Hubbard and GuiId.

Tom Dutro followed, excusing his presence and of Zeitz as fill-ins for the new program committee, and relying more on plate tectonics than data, explained the origin of the Arctic Basin and how Alaska got where it is.  In his talk, titled "The Nansen Fault Zone and its Significance in Arctic Paleogeography", Dutro chronologically summarized previous thought on the problem and then discussed the relative merits of underthrusting, rotation or sphenochasmation, and transform faulting.  The apparent biostratigraphic continuity between the Brooks Range - North Slope area and parts of the Queen Elizabeth Islands was pointed out as an important factor in the speaker's advocacy of transform faulting and of extension of the Nansen zone into Alaska.  For first hand observation, the area under consideration was passed around the audience in the form of the new National Geographic Globe.  Questions were asked by Dempsey (?), by Dave Harwood, by row 3, red tie, who later admitted being Ned Ostenso, by Guild, Anderson and Ostenso again.

In the final talk, Zietz took the "big stick" approach in his "Interpretation of an Aeromagnetic Strip Across the Northwestern U.S.".  With the introduction mentioning an "aeromatic strip" and the speaker pointing out the orientation of "fly tracks", the talk had immediate undivided attention.  Both the conspicuous northeast and northwest trend­ing magnetic patterns and the surficial structures, volcanics, and intrusives within the strip were attributed to various structural and compositional trends in the underlying basement rocks.  Further explana­tions were given for unusual magnetic anomalies and discontinuities within the area.  Ideas constituting considerable "promise for prospectors" included the apparent coincidence of pluton-related ore bodies and the points of intersection of magnetic and structural trends.

The single discussant of the talk was a distinguished but unidentified gentleman who had boldly usurped E-an Zen's usual seat, Row 2 on the aisle.  The meeting adjourned at 9:38. Attendance – 102

The 954th meeting of the Society was held in the John Wesley Powell Auditorium on January 26, 1972.  The real President Stewart called the meeting to order at precisely 8:00.  No distinguished visitors, other than President Stewart, were introduced.  The secretary read the minutes of the previous meeting and announced the election of four new members: Albert J.  Froelich of the Branch of Atlantic Environmental Geology, U.S.G.S.; Craig T. Rightmire, Water Resources Division, U.S.G.S.; Martin G. Seitz, a Fellow at the Geophysical Laboratory; and Thane McCulloh, with the Outer Continental Shelf Project, U.S.G.S.  The president announced the deaths of members Charles J. Hares of Boulder and William B. Heroy of Dallas.  He also noted the passing of Earl J. Fennell of the U.S.G.S.  A moment of silence was asked in their remembrance.  Rankin and others were summarily ordered into a holding pattern with President Stewart's announcement that no landing at the bar would be permitted during the course of meetings, (due possibly to the hazard of smog emanating from the platform, or to the potential of turbulence in the otherwise serene audience.).  The president appealed for leaders for field trips to the Coastal Plain, Bear Island and perhaps to survey local geomorphology.  Informal Communications were given first by Blair Jones, who embellished the president's table with a Department of the Inferior banner, consisting of the headline "Further Work is Indicated" arched over a seal of the late Bison bison, and second by Dan Appleman, who described the participation of the G.S.W. in the forms and minds of Stewart, Hearn, Wright, Bethke, Penny, Hanshaw and Appleman in a most successful two day field session designed to give the outdoor education specialists of the Montgomery County School System some background in geology, particularly that of the Catoctin - Middletown area where their camps are located.  The desirability of a similar session on the Coastal Plain was mentioned.

R.B. Neuman of the U.S.G.S. modestly thanked President Stewart for his most gracious and complimentary 5 second introduction and proceeded to discuss the "Paleontology of Early Ordovician Volcanic Islands".  It was suggested that the problem of extreme provincialism in Early Ordovician shelly facies and the subsequent breakdown of that provincialism into the diverse faunas found in the Middle Ordovician might well be due to the radiation of a fauna of wel1-homogenized, real story-telling brachiopods who had been hiding out all this time on volcanic islands, in northeastern North America, Wales and Norway.  Migration from this volcanic environment to adjacent continental shelves was made possible by the consumption of the intervening crustal plates according to the tectonic model of Dewey which consumption also removed most of the evidence for this or any other theory on the subject.  The talk was questioned by Stewart, by Epstein, by row 2 on the aisle, which seat had been summarily recovered by Zen from its unidentified usurper of the previous meeting, by Fiske and by Dutro.

The second presentation, by the triumvirate of John Lewis of George Washington University and Roy Bailey and Jules Friedman of the U.S.G.S., described the "1971 Eruption of Soufriére Volcano, St. Vincent, West Indies". 

Lewis led off, describing the geological setting and history of the volcano, especially detailing the 1902 eruption.  During his talk, the initial contact and skirmishes made previously by Neuman with the projection­ist broke out into open warfare.  Lewis’ first slide was in focus, so it was rejected immediately for another, from the end of his sequence, that was out of focus.  The fact that the first slide was also skewed to the left was only a poorly disguised political screen by the opposition.  After a devastating salvo of out-of-focus shots from the projection room, punctuated by minor eruptions from the by then steaming and nearly incandescent President Stewart, a unilateral cease-fire was called for from the floor.  A somewhat biased truce team was dispatched to inspect the enemy position while President Stewart promised that the autocracy of the projection booth would be severely tested if not indeed overthrown before the next meeting.

Roy Bailey continued on Soufriére, describing the events of the last three months of 1971, including the warming and the lowering of the crater lake, formation and growth of a lava dome in the middle of the lake, and the establishment of a geodimeter survey to measure possible swelling of the cone.  Two members of the geodetic crew narrowly escaped getting themselves into hot water when a large segment of the cone, which they had just sampled, slumped into the nearly boiling lake.  The discussion of Soufriére was con­cluded by Jules Friedman’s account of an infrared photographic survey, flown by the Navy, and intended to detect and monitor any particularly hot spots on the cone.  Finding none, subsequent surveillance was restricted to the crater lake.  An estimate of the total energy involved in the current activity placed it in class 5, equivalent to a middle sized Kilauea or Etna eruption and at only 10% of the 1902 eruption of Soufriére.  The talk was followed by a spiny question from George Ericksen, and by others from Hatch and Sato.

President Stewart adjourned the meeting at 9:53 with thanks to Tom Wright for his many fine programs during 1971.  Attendance 142.

The 955th meeting of the Society was klunked to order by President Stewart at 8:02 in the John Wesley Powell auditorium. Mr. Stancioff introduced Orvllle Russel of the Earth Satellite Corporation.  The minutes of the previous meeting were read and corrected.  The president announced that a new projector would be tried, and that speakers would be able to attempt to focus it themselves from the stage.  Further, that the Zen chair would be temporarily available In E-an's absence, that Mike Higgins would lead a field trip on Piedmont geology on the 18th of March (20 to 30 of those present showed interest in attending) and that John Hack would lead a trip to the Shenandoah Valley in late April.  Bob Neuman announced a Pick and Hammer function starring Vince McKelvey at the Twin Bridges Marriott Inn at 8:00 the 1st. of March.  Frank Whitmore, still sweeping up after last fall's G.S.A. Convention sold a large segment of the audience on the virtues of Marge Hooker's gastronomical compendium "Where Shall We Eat", and a reserved Dan Appleman, using the informal plea asked for volunteers to award G.S.W. sponsored prizes at local science fairs in late March and April.

Dan Krinsley of the U.S.G.S. "paid some price for progress" with the projector but still showed very well how "Geoenvironmental Maps the carto­graphic expression of applied geology" might bridge the troubled waters between the geologist and the non-geological user of information on the environment, natural resources, geological hazards and land evaluation. He was questioned by Stewart and Harbour.  John Dickey followed, and with great verbal dexterity described his solution to the plight of an undetermin­ed number of the "the Blind Men and the Ophiolite".  It appears that the ophiolite, a taxonomic calamity of oceanic habitat, apparently consisting of a melange of wehrlite, harzburglte, dunite and peridotite, with a tectonitic fabric woven in verticals and horizontals of stratiforms, podiforms, cumulates and intrusives, is reasonably safe from comprehensive description, at least for some time to come.  Following the talk, the president prescribed a chair for the speaker and a ten minute limit for the properly bespectacled and encaned Thayer.  A question was asked by Blake.

Charles Carter of Johns Hopkins University, using the old axiom the present is the key to the Cohansey, explained "Mio-Pliocene beach and Tidal-flat sedimentation, southern New Jersey", to have been the result of barrier island and tidal flat complexes migrating southeastward in response to upwarp of the region and regression of the sea.  Modern shore environments were examined and were shown to have equivalent facies in the Cohansey Sand.  The paper was questioned by Sheldon, Stifel, Anderson, Owens, Wones, Altshuler and Williams.  The meeting was adjourned at 9:28 P.M.  Attendance 132.

The 956th meeting of the Society was held! As the snow fell heavily outside the John Wesley Powell auditorium, President Stewart delayed his gavel until 8:10, in hopes that someone would show up.  To the stalwart and congenial gathering the secretary read the minutes of the previous meeting and announced the election to membership of Mr. Donald L. Kulow, EROS Program, U.S.G.S.; Mr. Stanley M. Remington, hydrologist with USAID; Mr. William S.  Kirk, Atlantic Environmental Branch, U.S.G.S.: Mrs.  Pene­lope Hanshaw, housewife branch, U.S.G.S.; and Mrs.  Elaine G. A. Weed, also with the U.S.G.S.  The president announced that we would Pick and Hammer at the Twin Bridges Marriott on March 1st, that the Northern Maryland Piedmont field trip would go on the 18th of March at 9:30 from the Maryland House on Rt. 95.  That transportation is to be private cars with the exception of Rankin who was given permission to bring his motor scooter, and that John Hack's field trip to the Shenandoah Valley will be April 15th and 16th.

Mary Mrose spoke for herself, George Ericksen and John Marinenko of the U.S.G.S.  in describing "Crystal Chemistry of the Calcium iodates in the System Ca(IO3)2-H2O".  Samples from the northern Chilean nitrate fields contained the anhydrous calcium iodate lauterite and a one hydrous prismatic form, which, after synthesis of the entire system, was diagnos­ed as new and named bruggenite.  Questions by Stewart, Toulmin, Leo, Peggy and Dan Appleman.

Andrew Graham of the Smithsonian Institution in discussing "Dating the Moon", by the use of Rb-Sr drew attention to differences in dates given by whole rock and single mineral analyses.  Samples from Apollo and Luna expeditions gave dates of 4.6 billion years for basaltic anchondritic soils, representing initial major differentiation on the moon, and 3.9 to 3.3 billion for younger maria-filling lavas, with apparently no significant activity having occurred since then.  Questions by Hensen (?), Stewart, Dan Appleman, Leo and Toulmin.

The third momentous event of the evening, following deference to Rankin and others for beer, was a viewing of the film "Rise and Fall of the Great Lakes" contributed by the Canadian Embassy, done by the Canadian National Film Board, starring woodsman and canoe and depicting, in a quazie-light hearted vein, the geological history and subsequent demise by pollution of the Great Lakes.  Adjournment at 9:35.  Attendance 38.

March 8, 1972

The 957th meeting of the Society was called to order by President Stewart at precisely 8:00 in the John Wesley Powell Auditorium. There were no announced visitors.  Minutes of the previous meeting were read and the election to membership of Gordon L. Kinney, Defense Intelligence Agency, Mrs. Sandra Holmes, Branch of Technical Illustration, U.S.G.S., Professor Cyril Ponnamperuma, Department of Chemistry, University of Maryland and Mr. Orville Russel of the Earth Satellite Corporation was announced.  Despite their recent election to the Society, members Kirk, Hanshaw and McCulloh were introduced and made welcome.  Our most distinguished blind man took the high road, skirting the ophiolite, to announce that nominations could be made by or through all members of the S.E.G. for that society's Lindgren award and that they were due by July 1st. Kinney voiced disapproval at Thayer's departure from the great ophiolite quest.  Someone mentioned something about astronauts and women in Building 8 in November, but a nasty rumor had it that it was really to be at Goddard in March, or was it the Grand Canyon, on Saturday? in 1869?

Tom Wright described work done by himself, Maurice Grolier and Don Swanson of the U.S.G.S. on "Chemical Variation Related to Stratigraphy in the Columbia River Basalt".  He showed a natural four part stratigraphic succession; that the stratigraphic breaks are also chemical breaks explain­ed by low pressure fractionation during storage of magma in the crust; that regional variation in TiO2 reflected inhomogeneities in the mantle, and that there was sufficient similarity between the youngest Columbia flows and the Snake River basalts to warrant further work in that area.

Questions by Stewart, Trent, Roedder, Lowman and Toulman, and a discourse by Thayer.  M. Clark Blake, Jr., U.S.G.S. "B.S.'d" (blue schist) his way through a discussion of "Plate Tectonics and High Pressure Metamorphism in New Caledonia", and took a great deal from at least our academic community in saying that indeed New Caledonia had the best b.s. on earth.  The northwest trending island, comprised of Permian to Eocene sediments and metasediments may have been overthrust by ultra mafic oceanic material, producing the Massif du Sud, the largest exposed periodotite mass on earth.  Jurassic and Eocene greywacke successively underthrust Triassic rocks along southeast dipping melange zones and, prior to the Upper Miocene, major transcurrent faulting took place along the western margin of the island.  Questions by Stewart, Woodring, Robertson and Thayer.

The final talk, by David B. Doan of the Earth Sciences Group, Inc. described his financially unsupported research on the "Evolution and Flow Characteristics of Atoll Channels in the Central Pacific". The non-random, geometrical, usually asymmetrical series of bifurcations seen in the evolution of channels was attributed to the interaction of relatively homeostatic hydrodynamic factors and metastatic biological factors such as coral and algal growth, tempered by space imitations in the lagoons and by faulting parallel to the margin of the reef.        Questions by Stewart, Fosburg, Roedder, Davis, Smith, and an unidentified friend of Coriolis.  With a reminder of the weekend field trip and the upcoming P.S.W. meeting, the president adjourned at 9:50.  Attendance 139.

March 22, 1972

The 958th meeting of the Society was held in the Jonn Wesley Powell Auditorium, called to order by President Stewart at 8:02 p.m. Mr. George Fause was welcomed back and Darryl Dunn of the University of Toledo was introduced. The minutes of the previous meeting were read and commented on as usual by the president. They were duly corrected informally.  In the midst of all his b.s.-ing, the secretary completely omitted the substance of Dr. Woodring's most penetrating question,"How did those fossils get in that blue-schist?", and Patrick Taylor fessed up to knowing Coriolis. Announcement was made of the election to membership of Laurie Joseph, a student at George Washington University, and of the re-election of Henry L. Berryhill, Jr., Assistant Chief Geologist for Marine Geology, U.S.G.S.

The President announced the Society's planned field trip April 15th and 16th to the Shenandoah Valley. Mary Mrose gave a blow by blow account of the awarding of the Society's signed certificates and books at the 1972 Northern Virginia Science Fair. The winner was an 8th grader whose project on meteoric impact obviously made a great impression on the judges.  Doug Kinny continued Ellis Yochelson's grave yard investi­gations with a well told tale of suspense and mystery. Who was Captain Lucas?  Spurred to the search by Professor and Mrs. Steiner of the University of Zagreb, Yugoslavia, Kinney visited Rock Creek Cemetery where he found the grave site and the literature, where he found Anthony Francis Lucas to have been the driller on the Lucas No. 1 at Spindeltop, Texas when it came in, in 1901. Through subsequent connection of that event and the Gulf Oil Company, the good Captain was summarily handed responsibility for Reston, Va.

William J. Sando of the U.S.G.S. traipsed all over Montana seeking the elusive "Precambrian Humbug".  From the Beltian Altyn and Seyeh Limestones in the Lewis Range to the Mississippian Alien Mountain Limestone of the Sawtooths, inch sized, light gray, circular patterns comprised of a spiral of oval cell-like markings on the surface of rock crevices led Sando and colleagues on a merry paleontological who-done-it. The culprit, a holarctic bee named Osmia, was finally apprehended, as were his relatives among the Anthidianea in South Africa, when Sando found and Hurd examined a set of slabs with pupae present! Shades of Sesame Street - co-op-er-ate!  Questions by Stewart and Hadley.

Dave Harwood of the Survey showed, in discussing "Tectonic Events in the West Side of the Berkshire Highlands, Massachusetts" that retreads really may have a lot of good miles in them, and look pretty well at that.  Referring to Bird and Dewey's model for the Evolution of the Appalachian Orogen, Harwood showed how Precambrian rocks, either floating or rooted, were thrust to the west in the late Ordovician over part of the western shelf quartzite carbonate sequence.  If I may use my editorial license, I would vote to renew Dave's artistic license for at least another year.  President Stewart continued his well established tradition of the quick query, followed by Robertson, Hadley and an unidentified oriental gentleman who assured the audience that although the Urals may have been a feasibility, there was positively no ground for rooting the Massachusetts Precambrian massif in China. William A. Fischer of the U.S.G.S. concluded the evening by suggesting a new look at the earth, by "Remote Sensing from Aircraft and Spacecraft", perhaps with the idea in mind that if we get far enough away it might not look so bad.  After pointing out the necessity of proper preliminary evaluation of the various approaches available, some significant factors of remote sensing were pointed out. The advantage of combined methods, such as photography and aeromagnetics, the usefulness of ephemeral factors such as changing vegetation, the possibilities of automatic data extraction and the removal of variables such as distortion and tonal changes were singled out.

In concluding, Fischer described the ERTS-A satellite which will go into a sun synchronous orbit in June. Vital information will be supplied to the broadest spectrum of scientists, if they can dig it out of the storage bank in Sioux Falls, South Dakota.  Questions by Stewart, Gabelman, Big Mac (Robert Hamberger) and Thayer. With announcement of the Petrology Club Meeting on the 28th and reminder of the 3 week interval before the next G.S.W. meeting on the 12th of April the president adjourned at 9:52.  Attendance 130.

The 959th meeting of the Society was held in the John Wesley Powell Auditorium, called to order at 8:02 by President Stewart. There were no announced visitors or new members. The minutes of the previous meeting, number 958, were read, disguised as those of meeting 957, whose minutes had in turn served for those of meeting 956, which meeting, under the Stifelian system, had indeed been held twice.

The president introduced field trip leader John Hack, who suggested wading shoes for his return to creekology in the Shenandoah valley that weekend, though in retrospect, life jackets might have been more in order. George Helz announced awards given by the society in the Prince Georges County Science Fair, first prize in the Earth Science Section going to Pam Welis for her exhibit on the geology of Maryland.

On his way to the airport, Walter Pitman of the Lamont-Doherty Geological Observatory, lead off the formal talks discussing the extension of the geomagnetic time scale made possible by new Pacific basin data, emphasizing a pulse of very rapid spreading contemporaneous with the great Cretaceous transgressions, all under the title of the "Geomagnetic Time Scale, Sea-floor Spreading, and the Closing of the Tethys".  Discussed by Helz, Tracey, Doan and Robertson.

William F. Cannon, of the U. S.G.S., talked on the "Interaction of Basement and Sedimentary Rocks During the Penokean Orogeny in Michigan", and showed that, (rather than the long-nosed folds that one might expect from the Penokean, secretary) roughly oval exposures of Archean basement rocks were surrounded by metasedimentary beds of the middle Precambrian that in places were cut out and dragged to vertical dips by a system of extremely high angle faults. The faulting was attributed by Cannon, because of its pattern, to differential vertical movement at depth rather than to compression in the crust.  Discussion by Guild, Trent and Douglass.

Metallogeny and the New Global Tectonics was the subject of the concluding paper by Philip W. Guild, in which he discussed the occurrence of metaliferous deposits both within and at the margins of the major tectonic plates.  Post-Eocene calk-alkaline magmas and associated ore deposits were shown to correlate well with the 100-200 kilometer depth contours on Benioff zones around the Pacific basin.  It was proposed that similar correspondence between older deposits and structures might be used to anticipate the margin of former plates.  Discussion by Warren, Leo, Calkins and Tracey. With the announcement that in spite of the A.G.U. the P.S.W. would meet on the following Wednesday, the meeting was adjourned at 9:50. Attendance 115.

The 960th meeting of the Society was held in the John Wesley Powell Auditorium, President Stewart sounding the gavel at 8:05 after a valiant but vain effort to hold out till the beer arrived.

Competition from a chamber music recital upstairs nearly did us in, depriving us, at least initially, of beer, chairs and a number of stalwart members.  Several of the latter were noticed easing into the room after our meeting just to make sure the second keg was not wasted. The pres­ident introduced Horst Pentinghaus and Herbert Kroll of the University of Munster and John Adams of the University of the West Indies. Norm Hatch introduced Mrs. Lisa Adams. The minutes of the previous meeting were read, and the election to membership of Kirn A.Walbe, a student at the University of Maryland, Robert A. Loney, U.S.G.S., and A.C. Huffman, a student at George Washington University was announced.

Bob Neuman brought greetings from the Pick and Hammer Club, announcing its joint sponsorship with the U.S.G.S. of a talk by Terry Edgar, Chief Scientist with Scripps Deep Sea Drilling Project on the Tectonic implications of the JOIDES program, Thursday, May 11, 2:00 P.M. G.S.A. auditorium.  Bill Leo gave summary in great depth of Earth and Astronomical Science Section awards at the D.C. Science Fair. The book Gems and Gem Minerals for first prize went to Michael Moroney, who showed that major stream pollutants kill guppies, and a whatjamacallit prize (G.S.W. Certificate) for second went to Rene Henkins who showed that Potomac River water also kills guppies. Mary Mrose was at her witty best in employing the informal plea to establish a pile of (Rhyolite, Orthorquartzite, Coal and Kimberlite Specimens) ROCKS in room G241H for teaching and demonstration purposes.  She proved beyond all doubt that any rock which happens by chance into the G.S.A. build­ing must, by definition, be a xenorock.  (The secretary suggested quietly to himself that Mary might try the R.O.T.C. Offices at the University of Maryland as a prime source of hand specimen rocks).

The formal program was begun by Dale Ritter of Franklin and Marshall College who presented some "Speculations Concerning the Competence of a Modern River Compared to its Pleistocene Ancestor." Rock Creek, part of the Yellowstone drainage which flows over Pinedale glacial gravel is less competent in its braided upper reaches and more competent where it is more consolidated down stream than its Pleistocene counterpart, as shown by the size of boulders in the stream bed. Variations in competency were related directly to channel patterns.  Questions by Denney and an unidentified friend of the Pleistocene.

Donald M. Burt of the Geophysical Laboratory followed, describing the "Geology of Some Skarn Deposits in Peru" which he evaluated for Cerro de Pasco Corporation, on a last ditch basis, before the leases were allowed to lapse.  Largely removed by glaciers and exposed by land­slides, the mountains of magnetite, massive garnet and copper seem destined to survive modern technology.  Even the mind of a Harvard man had to leave them high and dry.  Questions by Stewart, Gabelman, Leo, Hatch and Doan.

The concluding presentation, by a private citizen of Bowie, Maryland, described the trials and tribulations of involvement with "Politics and Garbage Geology", and is it not natural that one who has spent so many days of his life scrounging bugs from roadside ditches would become incensed at the probability of his beautiful Bellerophons being buried by beer cans, butts and bottles.  Ellis Yochelson complained of the lack of data on litter, as well as the difficulty of measuring it, of getting any money for it, of getting a deposit put on it and even of getting it all back in the hole it came out of. But, at a penny for twenty four cans, there is little wonder why Ellis has temporarily given up bottles and gone back to bugs, carrying the standard of the future - "Prepare to Meet Thy Recycler".  Questions by Helz and Sheldon.

With announcement of the next meeting in two weeks, adjournment came at 9:42. Attendance - 77.

With a special invitation to Dave Harwood, the 96lst meeting of the Society was called to order at 8:00 by President Stewart in the John Wesley Powel1 Auditorium.  Visitors Hezi Weiler and Tulio Prescatore were introduced by Dan Stanley.  The secretary read the minutes; there were no new members.  The death of Robert G. Bates, of the Geological Names Committee, U.S.G.S., was announced and the audience stood for a moment in remembrance.  After announcement of the Pick and Hammer program for the following day the formal program was begun.  W. Stewart McKerrow of Oxford University gave a most stimulating talk on "Silurian Paleogeography of the Caledonides and Northern Appalachians in the Light of Plate Tectonics" - a light, which thru the North Atlantic fog, seems still a bit hazy.

Evidence for a Silurian proto-Atlantic included turbidite belt through Frederickton, New Brunswick and Wales, bordered by Precambrian rocks which show considerably different Precambrian histories on the north and south and also by climatic differences north and south of the belts as shown by the involved fauna.  Andesitic basalts occurring sporadically on both sides of the turbidite belt suggested marginal subduction zones.  This was all well and good, but Professor McKerrow got into somewhat deeper water when he summarized that Acadian time saw a kiss between New Brunswick and South America. As the applause subsided Bill Oliver and Louis Pavlides respectfully questioned McKerrow's ideas on the grounds of biostratigraphy, including spat range and the distribution of volcanics in New Brunswick. The somewhat unlikely team of Stewart, Berdan and Kauffman discussed at some length question of which, among ostracods, brachiopods or trilobites, could spit the furthest and whether any of them could have spat across the Silurian Atlantic.  Kauffman was just about to get his Cretaceous oysters into the malay when Stewart opted to go on to the next paper.

Robert Finkelman of the U.S.G.S. discussed "the Association of Manganese Nodules and Cosmic Spherules".  In a fascinating paper, composition occurrence and probable origins for both nodules and spherules were discuss­ed in detail as were the circumstances of their association, especially the high concentrations of spherules in very slow growing, deep water nodules with high nickel content, as found in a wide area south and east of Hawaii.  Dave Stewart, Frank Whitmore and two suspiciously unidentified gentlemen, possibly agents from Dow or Monsanto, questioned the paper. In the concluding paper, Patrick Taylor, of the U.S. Naval Oceanographic Office used acoustical, gravitational, magnetic, core, and dredge data to intimately describe the "Anatomy of a Seamount".

Located northeast of Bermuda, in the New England chain, the Gillis Seamount produced 3 acoustical patterns: an opaque one, for the real, rather than sedimentary, rock of the seamount itself;  a structureless transparent marginal pattern produced by foraminiferal ooze containing some reworked warm water Cretaceous forms; and a stratified pattern from the abyssal apron, abutting or above the ooze, attributed to relatively recent turbidities and intervening red clays.  Description of dredged samples and topography derived from a multi beam sonar completed the story. Questions, in depth, at least 1000 fathoms, from Stewart, Kauffman, Stanley, Robertson, Kauffman again, going wild with two papers mentioning fossils in the same evening, and Wu.  At 9:40 Stewart adjourned one moving evening with the announcement of another in two weeks. Attendance 102.

The 962nd meeting of the Society was called to order at 8:04 p.m., Wed., May 24 by President Stewart in the John Wesley Powel1 Auditorium.  Minutes of the previous meeting were read and five new members were announced, including M. Clark Blake, U.S.G.S., Andrew F. Walsh, Department of Justice; Duane Brown, U.S. Army; David J. Brooks, Allied Research Associates, Inc.; and Miss Suzan Tufts, U.S.G.S., W.T.R.U.

Bob Newman announced the Maryland National Capital Park and Planning Commission objective to preserve type sections and key outcrops in Prince Georges and Montgomery Counties and asked the membership to contribute knowledge of additional sites of value. President Stewart announced the National Science Fair Winners in Earth Science, second prize for which was summer employment by the U.S.G.S.

Reversing the speaking order on the announcement, Bryan Isacks of Cornell, talked first on "Recent Studies of Earthquakes and Plate Tectonics", a discussion of suboceanic lithospheric plate behavior and forces of convection in the mantle.  Seismic evidence indicates both continuity and discontinuity of lithospheric slabs in the mantle to a depth limit of about 700 km.  Due to phase change at certain depths along subduction zones, great excess of mass may cause slabs of lithospheric crust to be pulled down under their own weight.  The resulting tension may then pull a slab apart, as evidenced by large gaps in the distribution of earthquake foci along the zone. Conforma­tion of the zone of foci shows sharp bending of some descending plates. Shallower quakes are largely tensional, deeper ones are compressional, possibly providing evidence for a strong mesosphere beneath a weaker asthenosphere. Among the numerous discussants of the paper in the approximate order of their first appearance were Erickson, Sohn, Blake, Stewart, Helz, Newman, Kleimmik, Zen, Woodring and Cohee.

While Isacks drifted off to the airport, John Dewey of SUNY at Albany posed the question "When Did Plate Tectonics Start?" and looked for the answer by comparing various orogenic belts to each other and to the modern oceanic floor.  Special emphasis was given to the late Precambrian to Ordovician rocks in Newfoundland.  Although well developed ophiolite sequences are not apparent in rocks older than 600 million years, Precambrian rocks in such places as west Africa and Tibet show evidence of plate tectonics as early as 2 billion years ago.

Questions by Doug Rankin, Thayer and Woodring.  The 154 enthusiastic attendees adjourned to the bar at 9:50.

With the meek request of "LET'S GO!" President Stewart gaveled the 963rd meeting of the Society to order at 8:00 in the John Wesley Powell Auditorium.  His special welcome to all the A to W people from the G.S.A. building, whose meeting notices had not made it past their mail room, was echoed by cries of "well done" and "right on";  Visitors Eiji Izawa of Kyushu University and Shungo Yui of Akita University, Japan were introduced by Paul Barton, Bill Oliver introduced Jerzy Federowski of the Polish Academy of Sciences, John Gableman introduced the entire Canadian Mineral Exploration Staff of British Petroleum Minerals, Ross Aiken, Derek Taylor, Josi Nikhanj, and Don Mustard. Frank Jacobeen introduced Bob Hiegesell of Washington Gas, Irv Breger introduced Jose Honarez of the University of Miami and Walter White exposed Charles Anderson.

Minutes of the last spring meeting were read and approved and the election of 6 new members was announced.  They include Morris Deutsch, EROS Program, U.S.G.S,  Dr. Bevan French, N.S.F., Mr. John McLane and Mr. Joseph Chernosky of the Experimental Geochemistry and Mineralogy Branch,  U.S.G.S., and Mr. Roger W. Swanson and Miss Marylyn L. Hubert of the Geologic Names Committee U.S.G.S.

The deaths of J.R. Randolf and W.T. Pecora were announced and the membership stood silently in remembrance.  The president asked for positive response to second and final unpaid dues notices and announced a Coastal Plain field trip for the 18th of November.  E-an Zen reported on the spring Penrose Conference on the Northern Appalachians, draw­ing special attention to a brilliant aeromagnetic map and four litho-logic maps of New England.

Starting the regular program, B.J. Hensen of the Geophysical Lab came part way out from behind his hair to describe "Divariant Reactions Involving Cordierite and Garnet as Pressure-Temperature Indicators". The two minerals coexist in a wide range of metamorphic rocks and can help determine the pressure-temperature conditions of the rock's formation.  The changes in divarient fields induced by iron and magnesium were considered.  Questions by Stewart and Zen.

John Gabelman of the A. E.G. discussed the "Evolution of a Metallotectonic Concept".  Using a model based on zoned ore deposits in Colorado, he proposed that mineralization gradients in the entire western Cordillera, the Appalachians, New England and Europe may fit patterns generated and controlled by plate tectonics.  Discussion by George Erickson, and Virgil Trent.  This being election time, an invitation to Phil Guild to debate the issue was understandably flatly refused.

Gordan Wood of the U.S.G.S., and A.A.P.G., speaking from a right height podium and overcoming an apparent low angle thrust in his slides discussed the "Tectonics of the Folded Appalachians of Pennsylvania as Deduced from the Anthracite Region." Structures of the system, from southeast to northwest were characterized, the tectonic history of the region was outlined and conclusions reached therefrom were expanded to include the entire eastern poverty belt.  Among many consequences of an extensive Taconic age Decollement, was the possibility of 80-100,000 square miles of Cambrian and Ordovician petroliferous facies underlying the western piedmont.  Rockville may have a gusher yet!  Discussion by Frank Jacobeen, Doug Rankin, Dave Doan and Avery Drake.  144 members and guests adjourned for refreshments at 9:50.

The 964th meeting of the Society was called to order by President Stewart at 8:03 p.m. in the John Wesley Powell Auditorium, 2170 Florida Ave., N.W. Washington, D.C. Bob Neuman introduced Gil Killing of Univer­sity College, Wales.  The minutes of the previous meeting were read and approved after correction by Avery Drake. The death of Peggy M. Berthaud of the U.S.G.S. was announced and the membership stood in silent remembrance. Announcement was made of the Nov. 18th field trip to Betterton, Md. to be led by Menard, Owen and Sohl. A weather date of December 2 was mentioned despite its non-applicability to anything less than waist high snow. The Nov. 15 deadline for abstracts for the N.E. Section GSA Meeting was announced.

Fifteen newly elected members were announced including Joseph M. Botbol, Allen L. Clark, Lawrence J. Drew, and Earl Irving of the Office of Resource Analysis, U.S.G.S.;  Eric A. Force and Nancy A. Wright of the Branch of Eastern Mineral Resources, U.S.G.S., Sandra Clark of the Office of Mineral Resources, U.S.G.S., Lucy M. Force, Eastern Environmental Geology, U.S.G.S., William A. Wright, Office of International Geology, U.S.G.S., Gordon P. Eaton, Assistant Chief for Geochemistry and Geophysics, U.S.G.S., Robert M. Hamilton, Assistant Chief for Earthquake Geophysics, U.S.G.S., George Lewis Meyer, Office of Radiation Programs, Environmental Protection Agency, Mrs. Penny Wetlaufer, ERTS Program, U.S.G.S. and Kenneth McGee, E G & M Branch, U.S.G.S.

Doug Rankin employed the informal objection in questioning the place of beer in the chair's pitcher, apparently being unaware of its far superior fire quenching power, especially for your smaller spontaneous type confla­grations. When duly reminded of this fact by the chair, Mr. Rankin, momentarily thwarted, withdrew, possibly to recoup for a future attempt against next year's regime. Remember well, Mr. Chairman, only you can prevent podium fires.

The regular program was begun by W.R. Keefer of the U.S.G.S. who described the Structure and Geologic History of Yellowstone National Park an appropriate talk, as this year is its 100th Anniversary. The talk detailed the park's stratigraphic column, as well as the structural, volcanic, and glacial events recorded there. And naturally, it featured your first class national park type slides. Questions by Helz, Stewart twice, Tracey, and George Sellers.

The second and third papers were presented consecutively by William E Davis, on Geological and Engineering Aspects, and by James F. Bailey on Hydrological Aspects of the Buffalo Creek Flood. Both speakers are with the U.S.G.S. Their subject was a dramatic one - Would you really expect an intentionally leaky dam, made of unstable coal waste, built on sludge, 250 feet high, on fire, with no spillway and 17 ½ million gallons of water suddenly behind it, to just sit there? It was not too surprising that 125 people were killed, 100 million dollars damage done and that a valley of horror was created along Buffalo Creek in Logan County, W. Va. last winter. Bare house foundations, twisted steel rails and imbricately stacked cars resulted from the 80,000 cubic foot per second discharge that occurred when the dam failed.

Questions by Taylor, Simkin and Wood. Meeting adjourned at 9:50, attendance 133.

The 965th meeting of the Society was called to order at 8:09 in the Powell Auditorium by a president who was fighting to suppress those well known symptoms that any human tends to acquire when he locks his brief case in the trunk of his car and then proceeds to loose the key to said trunk.

Dick Sheldon introduced Omar Raup and Bill Maple both with the U.S.G.S. in Denver, Bill Oliver introduced Yul Kriz of Czechoslovakia, King Hubbard introduced his assistant Jerry Karaganis, George Stoert introduced Frank Clagget of the American Petroleum Institute, E-an Zen introduced Alan Thompson of Manchester, England and President Stewart, still stalling for time, looked around for a friend in the audience and found Blair Jones.  The secretary read the minutes of the last meeting, announced the 5 newly elected members including William M. Reid of the Environmental Protection Agency, Mrs. David Larrabee, Stewart Marsh, a student at George Washington University, and Eleanor Keefer and Claire Davidson of the Office of Resource Analysis U.S.G.S. and further announced the council's slate of Society officers for 1973.  The deaths of Patsy B. Smith and W.D. Johnson were announced.

Malcolm Ross, Finance Committee Chairman mentioned planned changes in the G.S,W. Health Insurance Program and passed the buck on any problems with that to the "Administrator" in the white pages. Dan Appleman announced a Pick and Hammer Social Evening on December 1st. entitled China Today, and at about that point, Rankin played his hand.  Using his uncanny ability to psych out the opposition,-recognizing the president's unabated state of anguish, and the secretary's continued incapacitation from trying to spell the name of yet another one of Bill Oliver's Slovakian colleagues, Rankin advanced stealthily to the stage and in a brazen frontal assault ripped the cloth from, and boldly raped the Chair's Pitcher, filling his glass with beer and slinking off into the impersonality of the crowd to gloat over his conquest of the hapless and defenseless chair.

Roy Lindholm asked any members of the A.A.P.G. who were present to fill out a form of questions regarding that organization, and the President, whose notes had been miraculously extricated from the trunk of his car by the 1st. Vice President (using your standard size, class A crowbar) reannounced the Betterton Field trip for the 18th of November, There being no informal communications, the regular program followed with James W. Head of Bill Labs explaining "Geological Objectives of the Apollo 17 Mission to the Taurus-Littrow Region of the Moon - Pre-mission Prejudices." The geological aspects of this field trip will be greatly enhanced by having geologist Jack Schmitt along, especially since he has already been told by the engineers exactly which boulders to sample. Question by Stewart.  John Pojeta of the U.S.G.S. followed describing the reasons for his recent decision to establish "A New Class of Paleozoic Bivalve Molluscs".  He adroitly retained these fellows as molluscs, while at the same time kicking them out of all established classes, especially clams and those tricky two piece snails.  Questions by Roedder and McKelvey.

James E. Wilson, President of A.A.P.G. and Vice President for Exploration of the Shell Oil Company concluded the evening with a talk on "the Road Ahead in Petroleum Exploration - Where Does It Go?", mentioning primarily the consequences of our passing from a state of oil sufficiency to one of imminent and rapidly increasing dependency on other nations to meet our needs.  The talk may have raised a few more questions than it answered, at least from Peggy Appleman, Ross, McKelvey, Neuman, Roedder, Lindholm, Jacobeen and Henbest.

Adjournment 10:10.  Attendance- 138.

President Stewart called to order the 966th meeting of the Society at 8:03 p.m.  He introduced Paul Ribbe of V.P.I. & S.U. and announced the death of W. H. Condon.  The minutes of the preceding meeting or read an approved, and election to membership of the following eight persons was announced; Pat Lane, and undergraduate student at the University of Maryland, John D. Frantz, Floyd N. Hodges, Yoshikazu Ohashi, and George T. Stone of the Geophysical Lab.  Miss Rita Monahan of Washington technical reports unit of USGS, Paul H. Ribbe, geology Department, V.P.I. & S.U. and John R. Holloway of the chemistry department, Arizona State University.

Frank Whitmore announced the AAA’s meeting on December 26 -30th, the last one for them at Christmas time, and King Hubbard, speaking on behalf of Peter Wylie, editor of the Journal of Geology, employed the informal plea for papers, since the Journal is in need and Wylie is tired of writing.

At 8:15, with most of the important business of the year end of the way, President Stewart sailed off into the sunset of his term on his "spontaneous Noah's Ark, the feldspars."  He chose a rather ancient arc of post Lower but pre-Middle Devonian age by his own admission.  But in it was a fascinating bunch; sanadines and perthites, orthoclases and albites, and even those pesky peristerites.  Telling all these fellows apart got to be a bit of a problem, even for old D. S. Noah - especially since unmixing lamellae in some cases involved only a few angstroms, but no one had some tricks up his sleeve; after a little HF etching, some microsand-blasting with ionized argon, and a bit of photoemission electron microscopy, he had those feldspars all sorted out and lined up for some truly remarkable photographs.  All in all in most exhilarating sail.  At 9:00 the meeting was adjourned for beer and the 80th annual meeting which followed.  Attendance 196.

80th Annual Meeting

Geological Society of Washington

Only after the acquisition of and complete consumption by the attending membership of an extra keg of beer, the President Dave Stewart, at 9:10 p.m. on December 13, 1972, summon the 80th Annual Meeting of the Society to order.  Council Secretary Huebner and entranced most of those present with 10.25 minutes worth of 79th Annual Meeting minutes, to which the group plead no contest, accepting them by default.  The Annual Report of the Secretaries was followed by a brief informal moment of silence, probably from relief at the final passing of both Huebner and Stifel from active duty at meetings.

Treasurer Peggy Appleman’s report noted receipts for 1972 of $4469, disbursements of $4246, a net cash balance of $223, and holdings in the endowment fund of $3676 as of December 13, 1972.  Total Society assets of $3899 were decreased by $174 during 1972.  Membership totaled 1063, down 8 from the preceding year.

Auditing Committee Chairman, Ralph Christian reported the Society's accounts in good order

Malcolm Ross noted, for his Finance Committee, that there appeared no reason to have to raise dues in the next couple of years.  He also noted the Society's inability to raise money, citing our $300 deficit on guidebooks for the 1971 G.S.A. meeting, while that society was clearing $30,000.  Past-President White moved acceptance of the two preceding reports and they were duly approved.

On behalf of the public service committee, Chairman Dan Appleman thanked science fair judges and proclaimed the success of a two-day, Montgomery County Earth Science Teacher and Supervisors Seminar on Catoctin Mountain.

The awards committee, under the table guidance of Dave Harwood, presented the great Dane award to Mary Mrose for her eloquent plea for rocks, and the best paper award to John Dickey of Cambridge, Mass. for his paper titled "The blind man and he ophiolite."  A promise went to John along with his check that the inscribed cut would be forthcoming as soon as it could be rescued from Wendell Duffield’s stored belongings.

After the President's call for the sleeping Bear Award, Steve Huebner, finding himself no longer able to control his emotions, got up quietly from his chair and, with as little commotion is possible, walked once around the room.  With his nerves of us assuaged, he returned to his seat.  Blair Jones then arose to present one of the most cherished awards the Society can bestow.  After excuses for attempting to stack his committee with geochemists and explaining the nature of the award, Blair proceeded to summarily dismiss such obvious contenders as President Stewart, Secretary Stifel, A.A.P.G. President Wilson, and a host of deserving paleontologists including Dutro, Newman, Sando, and Yochelson.  Harwood, Thayer, Burt, and the protectionist met similar fates.  The award finally went to Doug Rankin for, and I quote "boldly marching forward to establish the right of the membership to quench the fire of a consuming thirst from the privileged sanctions of the executive extinguisher."  Having been ridiculed by this little caper, the present lame-duck Council Secretary gives fair warning to the Meeting Secretary elect take heed Mr. Rankin, in a few minutes the shoe will be on the other foot.

With no new business to conduct, the meeting proceeded to the election of officers for the coming year, with the membership giving unanimous support to the Council slate.  Past President Stewart thanked outgoing Program Chairman Hatch and council members Allen, Douglas Finger, Roedder and Huebner, handed over the Budweiser gavel and unopened Roberts Rules to President Kinney and sat back to enjoy Kinney’s "inaugural address."

After reminding the membership that Stewart and Stifel had presided during the Year of the Rat, announcing a field trip for the coldest day in March, proclaiming sleeping Bear Rankin Program Chairman for the coming year, and promising great endeavors by the incoming administration, Kinney adjourned meeting at 10:10 p.m.

Respectfully submitted

Peter B. Stifel,

Council Secretary
