BUREAU OF ECONOMIC GEOLOGY ANNUAL REPORT - 1973 RESEARCH AND ADMINISTRATIVE OFFICES LABORATORIES Geology Building, Main Campus Balcones Research Center THE UNIVERSITY OF TEXAS AT AUSTIN W. L. FISHER, DIRECTOR BUREAU OF ECONOMIC GEOLOGY The Bureau of Economic Geology is a research bureau of The University of Texas at Austin; it also functions as a quasi-state agency. Established in 1909, it has for 64 years been recognized as the Texas State Geological Survey; its Director fills the position of State Geologist. The Bureau of Economic Geology also serves as a member agency of the State Interagency Council on Natural Resources and the Environment. The Bureau is engaged in research, both basic and applied, and public service in Texas geology and natural resources. The program of applied research is focused on mineral and land resources, environmental and conservation problems, and engineer- ing problems. The Bureau's efforts in systematic geologic mapping are designed to produce geologic and special derivative maps at several scales for all those concerned with resources and land use in Texas. The Bureau participates in other University research efforts in the fields of resources and earth sciences, including those of the Center for Research in Water Resources and the Marine Science Institute at Port Aransas. These two organizations, with the Bureau, constitute The University's Division of Natural Resources and Environment. The Bureau publishes major reports in The University of Texas Publication series and maintains its own series of Reports of Investigations, Atlases, Geologic Quadrangle Maps, Geological Circulars, Mineral Resource Circulars, and Special Publications. A complete list of publications is available on request. The geologic data developed by the Bureau of Economic Geology, in the form of scientific reports and geologic maps, are used by many state and federal organizations in carrying out investigations in the public service. The Texas Water Development Board, Texas Highway Department, Parks and Wildlife Department, Texas Industrial Commission, Railroad Commission, General Land Office, Gov- ernor's Office, Attorney General's Office, and numerous other state departments, boards, conservation organizations, water districts, councils of government, and chambers of commerce utilize Bureau publications and services on both a formal and informal basis through interagency contracts and staff conferences. The Bureau also cooperates with federal agencies, such as the Geological Survey, National Aero- nautics and Space Administration, Environmental Protection Agency, Bureau of Reclamation, Corps of Engineers, and National Park Service. The mineral and geological information service offered by the Bureau of Economic Geology is used by public officials, private groups, corporations, and citizens through correspon- dence and conference. PUBLICATIONS IN 1973 In its role as a public geologic research unit, the Bureau of Economic Geology disseminates the results of research programs and projects primarily through its own publication series. During the 64-year history of the Bureau, nearly 700 reports, bulletins, and maps have been published covering all major aspects of the geology and natural resources of Texas. To date, approximately one million publications have been distributed, principally through direct sales. Distribution and publication inventory have steadily increased through the years. Bureau publications are made available to interested persons at a price determined to recover printing costs. A complete list of publications of the Bureau of Economic Geology is available on request.

    NATIONAL HISTORIC LANDMARKS Dr. Harry A. Butowsky GEOLOGY THEME STUDY Page 1 Geology National Historic Landmark Theme Study (Draft 1990) Introduction by Dr. Harry A. Butowsky Historian, History Division National Park Service, Washington, DC The Geology National Historic Landmark Theme Study represents the second phase of the National Park Service's thematic study of the history of American science. Phase one of this study, Astronomy and Astrophysics: A National Historic Landmark Theme Study was completed in l989. Subsequent phases of the science theme study will include the disciplines of biology, chemistry, mathematics, physics and other related sciences. The Science Theme Study is being completed by the National Historic Landmarks Survey of the National Park Service in compliance with the requirements of the Historic Sites Act of l935. The Historic Sites Act established "a national policy to preserve for public use historic sites, buildings and objects of national significance for the inspiration and benefit of the American people." Under the terms of the Act, the service is required to survey, study, protect, preserve, maintain, or operate nationally significant historic buildings, sites & objects. The National Historic Landmarks Survey of the National Park Service is charged with the responsibility of identifying America's nationally significant historic property. The survey meets this obligation through a comprehensive process involving thematic study of the facets of American History. In recent years, the survey has completed National Historic Landmark theme studies on topics as diverse as the American space program, World War II in the Pacific, the US Constitution, recreation in the United States and architecture in the National Parks.

  • What We Know About Subduction Zones from the Metamorphic Rock Record
    What we know about subduction zones from the metamorphic rock record Sarah Penniston-Dorland University of Maryland Subduction zones are complex We can learn a lot about processes occurring within active subduction zones by analysis of metamorphic rocks exhumed from ancient subduction zones Accreonary prism • Rocks are exhumed from a wide range of different parts of subduction zones. • Exhumed rocks from fossil subduction zones tell us about materials, conditions and processes within subduction zones • They provide complementary information to observations from active subduction systems Tatsumi, 2005 The subduction interface is more complex than we usually draw Mélange (Bebout, and Penniston-Dorland, 2015) Information from exhumed metamorphic rocks 1. Thermal structure The minerals in exhumed rocks of the subducted slab provide information about the thermal structure of subduction zones. 2. Fluids Metamorphism generates fluids. Fossil subduction zones preserve records of fluid-related processes. 3. Rheology and deformation Rocks from fossil subduction zones record deformation histories and provide information about the nature of the interface and the physical properties of rocks at the interface. 4. Geochemical cycling Metamorphism of the subducting slab plays a key role in the cycling of various elements through subduction zones.

  • Deep Groundwater and Potential Subsurface Habitats Beneath an Antarctic Dry Valley
    ARTICLE Received 21 May 2014 | Accepted 2 Mar 2015 | Published 28 Apr 2015 DOI: 10.1038/ncomms7831 OPEN Deep groundwater and potential subsurface habitats beneath an Antarctic dry valley J.A. Mikucki1, E. Auken2, S. Tulaczyk3, R.A. Virginia4, C. Schamper5, K.I. Sørensen2, P.T. Doran6, H. Dugan7 & N. Foley3 The occurrence of groundwater in Antarctica, particularly in the ice-free regions and along the coastal margins is poorly understood. Here we use an airborne transient electromagnetic (AEM) sensor to produce extensive imagery of resistivity beneath Taylor Valley. Regional- scale zones of low subsurface resistivity were detected that are inconsistent with the high resistivity of glacier ice or dry permafrost in this region. We interpret these results as an indication that liquid, with sufficiently high solute content, exists at temperatures well below freezing and considered within the range suitable for microbial life. These inferred brines are widespread within permafrost and extend below glaciers and lakes. One system emanates from below Taylor Glacier into Lake Bonney and a second system connects the ocean with the eastern 18 km of the valley. A connection between these two basins was not detected to the depth limitation of the AEM survey (B350 m). 1 Department of Microbiology, University of Tennessee, Knoxville, Tennessee 37996, USA. 2 Department of Geosciences, Aarhus University, Aarhus 8000, Denmark. 3 Department of Earth and Planetary Sciences, University of California, Santa Cruz, California 95064, USA. 4 Environmental Studies Program, Dartmouth College, Hanover, New Hampshire 03755, USA. 5 Sorbonne Universite´s, UPMC Univ Paris 06, CNRS, EPHE, UMR 7619 Metis, 4 place Jussieu, Paris 75252, France.
