Summary of ground-water conditions in the Jaffna Peninsula, Republic of Sri Lanka, with a plan for investigating feasibility of ground-water development
Harold Meisler
1977, Open-File Report 77-558
Ground water in the Jaffna Peninsula of Sri Lanka, Ceylon, occurs within solution openings of the Jaffna Limestone of Miocene age. The freshwater forms a complex of lenses up to 25 meters thick overlying saline water derived from the sea. Salt-water intrusion and upconing of the salt water has occurred...

Geologic interpretation of a radioactivity anomaly near the west fork of the Buckland River, western Alaska
Thomas P. Miller
1977, Open-File Report 77-372
A large part of western Alaska has been included in a uranium- thorium metallogenic province (Clark and others, 1974; Miller and Bunker, 1976; Miller, 1976) chiefly because of the occurrence of uraniferous plutonic rocks with local concentrations of uranium minerals. Recently, however, anomalous amounts of uranium and thorium have been...

January 1977 water levels, and data related to water-level changes since 1950, western Kansas
Marilyn E. Pabst
1977, Open-File Report 77-264
This report contains basic data on water-level measurements in observation wells in western Kansas. Most of the measurements were made in January 1977; a few were made in December 1976 and in February 1977. The measurements were made in mid-winter when pumping was minimal and water levels had recovered from...
Hydrologic data for Cow Bayou, Brazos River Basin, Texas, 1975

The U.S. Soil Conservation Service is actively engaged in the implementation of flood- and soil-erosion reducing measures in Texas under the authority of. "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found a...
Progress report on uranium investigations in the Zane Hills area, west-central Alaska
Thomas P. Miller, Raymond L. Elliott
1977, Open-File Report 77-428
The Zane Hills pluton underlies a mountainous area of about 460 km2 in west-central Alaska and is locally enriched in uranium and thorium (Miller and Ferrians, 1968; Miller, 1970; Staatz and Miller, 1976). While over 90 percent of the pluton consists of granodiorite with average contents of uranium and thorium,...
Hydrologic maps and data in the Mimbres Basin, New Mexico
John S. McLean
1977, Open-File Report 77-314
This report was prepared by the U.S. Geological Survey in cooperation with the New Mexico State Engineer Office and lists well and spring data, including well locations, water levels, well yields, and chemical analyses of well and spring water. Maps in the report show well locations, water-level contours, and water-level...
Lithium in the brines of Fish Lake Valley and Columbus Salt Marsh, Nevada
C. L. Smith, Allen L. Meier, H.D. Downey
1977, Open-File Report 77-54
Analyses of waters-from springs in Nevada have led to the identification of an area containing anomalous amounts of lithium northwest of the Clayton Valley-area. Fish Lake Valley and Columbus Salt Marsh contain waters having, relatively high lithium and potassium concentrations. At least a part of these waters is probably derived...

Effect of channel material on width-discharge relations for perennial streams, with emphasis on streams in Kansas -- a progress report
W. R. Osterkamp
1977, Open-File Report 77-38
Using consistent procedures for width measurement at established streamflow-gaging stations, data were compiled to develop a power-function relation between width and mean discharge for high-gradient perennial streams. High-gradient channels, which generally exhibit low variability for most factors influencing the width-discharge relation, were selected to define a standard exponent in the...
Hot springs of the central Sierra Nevada, California
Robert H. Mariner, T. S. Presser, William C. Evans
1977, Open-File Report 77-559
Thermal springs of the central Sierra Nevada issue dilute to slightly saline sodium chloride, sodium bicarbonate, or sodium mixed-anion waters ranging in pH from 6.4 to 9.3. The solubility of chalcedony appears to control the silica concentration in most of the spring waters. Fales Hot Springs may be associated with...

Organic geochemistry, lithology, and paleontology of Tertiary and Mesozoic rocks from wells on the Alaska Peninsula
Hugh James McLean
1977, Open-File Report 77-813
Core chips and drill cuttings from eight of the nine wells drilled along the Bering Sea lowlands of the Alaska Peninsula were subjected to lithologic and paleontologic analyses. Results suggest that at least locally, sedimentary rocks of Tertiary age contain oil and gas source and reservoir rocks capable of generating...

Background studies for appraising subsidence in the Texas Gulf Coast region
B. E. Lofgren
1977, Open-File Report 77-412
Significant ground movement has accompanied the extraction of large quantities of fluids from the subsurface at many localities. The possibility of both horizontal and vertical ground movement--subsidence, fissuring, growth faulting--in the Gulf Coast region, caused by the withdrawal of large volumes of deep formation fluids, is of major concern.Although widespread...
