  • B15 the Once Four Named Pleistocene Glacial Stages < Tills >
    METHODOLOGY 97 b15 The once four named Pleistocene Glacial Stages < tills > In lapidary inscriptions, a man is not upon oath. —Samuel Johnson.1 Two major schemes of harmonization [of Scripture and geology] were developed and refined during the nineteenth century: these were the gap and day-age interpretation of Genesis 1. —Davis A. Young.2 A. Bernardi in 1832 envisaged Europe covered by ice. This was to explain: “How rock fragments originating in the north came to where one finds them strewn and in mounds in Northern Germany and neighboring lands.”3 For that time, Louis Agassiz’s botanist/poet friend Karl Schimper in 1837 coined the term Eiszeit (ice age). Earlier, apposed to such, Agassiz had studied existing glaciers and their products: erratic boulders, glacially scoured, striated and polished bedrock, glacial moraines, and glacially modified landscape. However in 1837 he issued his famous “Neuchâtel Discourse ” volta-face. Materials formerly mapped as diluvium he reclassified as till and glacial outwash.4 In Britain, James Geikie in 1877 presented evidence of two glacial stages.5 In America, N. S. Shaler in 1889 presented evidence in New England of at least two ice sheet advances.6 In Europe, Albrecht Penck and Eduard Bruckner in 1909 noted remnants of four sets of river terraces in the outwash gravels in the northern foothill valleys of the Alps. These terraces can be correlated by their hydraulic heights. In Penk’s scheme, each accorded to a major advance of an otherwise diminishing ice sheet and so youngest is the lowest and oldest

  • The Glacial Geology of New York City and Vicinity, P
    Sanders, J. E., and Merguerian, Charles, 1994b, The glacial geology of New York City and vicinity, p. 93-200 in A. I. Benimoff, ed., The Geology of Staten Island, New York, Field guide and proceedings, The Geological Association of New Jersey, XI Annual Meeting, 296 p. John E. Sanders* and Charles Merguerian Department of Geology 114 Hofstra University Hempstead, NY 11549 *Office address: 145 Palisade St. Dobbs Ferry, NY 10522 ABSTRACT The fundamental question pertaining to the Pleistocene features of the New York City region is: "Did one glacier do it all? or was more than one glacier involved?" Prior to Fuller's (1914) monographic study of Long Island's glacial stratigraphy, the one-glacier viewpoint of T. C. Chamberlin and R. D. Salisbury predominated. In Fuller's classification scheme, he included products of 4 glacial advances. In 1936, MacClintock and Richards rejected two of Fuller's key age assignments, and made a great leap backward to the one-glacier interpretation. Subsequently, most geologists have accepted the MacClintock-Richards view and have ignored Fuller's work; during the past half century, the one-glacial concept has become a virtual stampede. What is more, most previous workers have classified Long Island's two terminal- moraine ridges as products of the latest Pleistocene glaciation (i. e., Woodfordian; we shall italicize Pleistocene time terms). Fuller's age assignment was Early Wisconsinan. A few exceptions to the one-glacier viewpoint have been published. In southern CT, Flint (1961) found two tills: an upper Hamden Till with flow indicators oriented NNE-SSW, and a lower Lake Chamberlain Till with flow indicators oriented NNW-SSE, the same two directions of "diluvial currents" shown by Percival (1842).

  • A Partial Glossary of Spanish Geological Terms Exclusive of Most Cognates
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY A Partial Glossary of Spanish Geological Terms Exclusive of Most Cognates by Keith R. Long Open-File Report 91-0579 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. 1991 Preface In recent years, almost all countries in Latin America have adopted democratic political systems and liberal economic policies. The resulting favorable investment climate has spurred a new wave of North American investment in Latin American mineral resources and has improved cooperation between geoscience organizations on both continents. The U.S. Geological Survey (USGS) has responded to the new situation through cooperative mineral resource investigations with a number of countries in Latin America. These activities are now being coordinated by the USGS's Center for Inter-American Mineral Resource Investigations (CIMRI), recently established in Tucson, Arizona. In the course of CIMRI's work, we have found a need for a compilation of Spanish geological and mining terminology that goes beyond the few Spanish-English geological dictionaries available. Even geologists who are fluent in Spanish often encounter local terminology oijerga that is unfamiliar. These terms, which have grown out of five centuries of mining tradition in Latin America, and frequently draw on native languages, usually cannot be found in standard dictionaries. There are, of course, many geological terms which can be recognized even by geologists who speak little or no Spanish.

  • From the Northern Ice Shield to the Alpine Glaciations a Quaternary Field Trip Through Germany
    DEUQUA excursions Edited by Daniela Sauer From the northern ice shield to the Alpine glaciations A Quaternary field trip through Germany GEOZON From the northern ice shield to the Alpine glaciations Preface Daniela Sauer The 10-day field trip described in this excursion guide was organized by a group of members of DEUQUA (Deutsche Quartärvereinigung = German Quaternary Union), coordinated by DEUQUA president Margot Böse. The tour was offered as a pre-congress field trip of the INQUA Congress in Bern, Switzerland, 21– 27 July 2011. Finally, the excursion got cancelled because not enough participants had registered. Apparently, many people were interested in the excursion but did not book it because of the high costs related to the 10-day trip. Because of the general interest, we decided nevertheless to finish the excursion guide. The route of the field trip follows a section through Germany from North to South, from the area of the Northern gla- ciation, to the Alpine glacial advances. It includes several places of historical importance, where milestones in Quaternary research have been achieved in the past, as well as new interesting sites where results of recent research is presented. The field trip starts at Greifswald in the very North-East of Germany. The first day is devoted to the Pleistocene and Ho- locene Evolution of coastal NE Germany. The Baltic coast with its characteristic cliffs provides excellent exposures showing the Late Pleistocene and Holocene stratigraphy and glaciotectonics. The most spectacular cliffs that are located on the island of Rügen, the largest island of Germany (926 km2) are shown.

    Community Surface Dynamics Modeling System CSDMS 2.0 Final Report CSDMS 2.0 FINAL REPORT (2013-17) ANNUAL REPORT (2017-18) NSF COOPERATIVE AGREEMENT 1226297 1 Community Surface Dynamics Modeling System CSDMS 2.0 Final Report Executive Summary CSDMS (Community Surface Dynamic Modeling System) is a NSF-supported, international and community-driven effort to transform the science and practice of earth-surface dynamics modeling. CSDMS is now a Keystone component of the earth surface community. It is particularly needed in a complex, changing earth: the earth’s surface is where we will experience the change; the CSDMS modeling foundry has become essential in helping to anticipate future states and guide alternative futures. The broad overview of modeling-based research gained by CSDMS is of fundamental importance to the identification and implementation of interdisciplinary research connections. This CSDMS 2.0 Final Report (2013 to 2017) and Annual Report (2018) provides a review of the past six years of the CSDMS project. The report documents the organizational structure and finances (Chapters 1, 2, 9, 10), the cyber infrastructure advances (Chapters 3, 4, 5, 6, 8), education and knowledge transfer achievements (Chapter 7), and scientific accomplishments (Chapters 11). 2 Community Surface Dynamics Modeling System CSDMS 2.0 Final Report CSDMS2.0 Final Report Chapters 1 CSDMS Mission and Community 5 1.1 Mission & Goal 5 1.2 Science Questions and Community Functions 5 1.3 The CSDMS2.0 International Community 6 1.4 Institutional Membership 7 1.5
