The Alaskan Mineral Resource Assessment Program: Guide to information contained in the folio of geologic and mineral resource maps of the Chandalar quadrangle, Alaska
H. N. Reiser, W. P. Brosge, J. H. DeYoung, S.P. Marsh, T. D. Hamilton, J. W. Cady, N. R. D. Albert
1979, Circular 758
The Chandalar quadrangle in east-central Alaska was investigated by a multidisciplinary research group to assess the mineral resource potential of the quadrangle. This circular serves as a guide to and integrates with a folio of 10 miscellaneous field study (MF) maps and 2 open-file (OF) reports (table 1) concerned with...
Biological and microbiological assessment of the upper Chattahoochee River basin, Georgia
Bruce W. Lium, J. K. Stamer, T. A. Ehlke, R.E. Faye, R.N. Cherry
1979, Circular 796
Biological and microbiological studies were conducted by the U.S. Geological Survey as a part of the Intensive River-Quality Assessment studies of the upper Chattahoochee River basin, Georgia. Phytoplankton concentrations in cells per milliliter (cells/mL) were generally higher downstream from Atlanta than upstream. The highest concentrations, mostly blue-green algae, occurred in...
The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Talkeetna quadrangle, Alaska
Bruce L. Reed, G.C. Curtin, Andrew Griscom, S.W. Nelson, D.A. Singer, W. C. Steele
1979, Circular 775
The Talkeetna 1° by 3° quadrangle, which consists of about 17,155 km2 in south-central Alaska, was investigated by integrated field and laboratory studies in the disciplines of geology, geochemistry, geophysics, and Landsat data interpretation for the purpose of assessing its mineral resource potential. Past mineral production has been limited to...
Preliminary geology of the Blacktail Mountain drilling site, Flathead County, Montana
Jack Edward Harrison, Mitchell W. Reynolds
1979, Open-File Report 79-938
Five argillitic green beds that alternate with six argillitic purple beds in the upper part of the Spokane Formation of the Belt Supergroup of Proterozoic Y age were sampled by 22 shallow core holes. The holes were drilled on a hexagonal pattern over an area about 50 m wide and...
Ground-water data for Michigan, 1977
G.C. Huffman
1979, Open-File Report 79-332
The purpose of this report is to make available the 1977 records of water levels and related data for the principal aquifers of the State. These records and data provide a means for evaluating available ground-water supplies. Long- term records serve as a framework to which short-term records may be...
Water-resources investigations of the U.S. Geological Survey in Colorado; fiscal year 1979
1979, Open-File Report 79-402
Water-resources investigations of the U.S. Geological Survey in Colorado consist of collecting water-resources data and conducting interpretive hydrologic investigations. The water-resources data and the results of the investigations are published or released by either the U.S. Geological Survey or by cooperating agen-cies. This report describes the water-resources investigations in Colorado...
Progress report to the Arkansas State Highway and Transportation Commission for year ending September 30, 1978
Marion S. Hines
1979, Open-File Report 79-523
The economic design of bridges and culverts requires a knowledge of the magnitude and frequency of floods for all size drainage basins. In addition, an analysis of the hydrologic and hydraulic characteristics at specific sites where unusual circumstances exist is a prerequisite to design.The Arkansas State Highway and Transportation Commission...
Goal-seismic computer programs in BASIC: Part I; Store, plot, and edit array data
Wilfred P. Hasbrouck
1979, Open-File Report 79-242
Processing of geophysical data taken with the U.S. Geological Survey's coal-seismic system is done with a desk-top, stand-alone computer. Programs for this computer are written in an extended BASIC language specially augmented for acceptance by the Tektronix 4051 Graphic System. This report presents five computer programs used to store, plot,...
Analyses of surficial deposits, central Brooks Range, Alaska
Thomas D. Hamilton, James H. Trexler, James McCalpin
1979, Open-File Report 79-228
Seventy-nine sediment samples from the central Brooks Range were analyzed for grain-size distribution, shape and composition of grains, and other physical properties. Four statistical measures (sorting, mean diameter, skewness, and kurtosis) were then computed for the sand-to-clay size fraction of all samples.Fan sediments resemble the other alluvial-gravel deposits in consisting...
Preliminary catalog of earthquakes in northern Imperial Valley, California, October 1978-December 1978
V. Lamanuzzi, C.E. Johnson, P.T. German
1979, Open-File Report 79-930
The northern section of the Imperial Valley region in southern California is an area of known geothermal resources and high seismicity. To investigate the relationship between geothermal areas and earthquakes in the Imperial Valley, a 16-station seismic network was established in early 1973 by the U. S. Geological Survey. Six...
Monitoring crustal strain, Cerro Prieto geothermal field, Baja California, Mexico
Ben Elder Lofgren, Bruce L. Massey
1979, Open-File Report 79-204
Significant ground deformation may be occurring in the Cerro Prieto geothermal area, Mexicali Valley, Mexico, as a direct result of extensive withdrawals of geothermal fluid and of continuing tectonism. In order to measure the magnitude and rate of this deformation, three networks of precise geodetic control were established in 1977-78,...
Program objectives for the National Water Data Exchange (NAWDEX) for fiscal year 1980
Melvin D. Edwards
1979, Open-File Report 80-11
This report describes the proposed program objectives of the National Water Data Exchange (NAWDEX) for fiscal year 1980. These include NAWDEX program administration, NAWDEX services, water-data indexing activities, systems development, training, and the development of recommended methods for the handling and exchange of water data. ...
Trace element analysis of marine organisms by anodic stripping voltammetry (ASV)
Gary W. Hill
1979, Open-File Report 79-392
Trace element analysis of marine organisms has generally been conducted by (1) sophisticated instrumentation (e. g., atomic absorption), (2) complicated cookbook laboratory procedures utilizing a host of chemicals and glassware, or (3) a combination of the above. All these procudures present problems to the investigator. For example, analysis by methods...
