Depositional environments as a guide to uranium mineralization in the Chinle Formation, San Rafael Swell, Utah
Robert Lupe
1976, Open-File Report 76-283
Uranium deposits in the San Rafael Swell are related to sedimentary depositional environments in the Triassic Chinle Formation. The sedimentary textures resulting from depositional processes operating in lower energy environments appear to have influenced uranium mineralization. The Chinle consists of three fining-upward, fluvial-lacustrine sequences. Uranium mineralization is concentrated in the...
Water resources of the Big Fork River watershed, north-central Minnesota
Gerald F. Lindholm, John O. Helgesen, Donald W. Ericson
1976, Hydrologic Atlas 549
The Big Fork River watershed is one of 39 watershed units designated by the Minnesota Department of Natural Resources for evaluation of the State 's water resources. Included is an appraisal of the occurrence, quantity, quality, and availability of ground and surface waters. Water resources are not intensively developed anywhere...
Water resources of the Bighorn basin, northwestern Wyoming
Marlin E. Lowry, H. W. Lowham, Gregory C. Lines
1976, Hydrologic Atlas 512
This 2-sheet map report includes the part of the Bighorn Basin and adjacent mountains in northwestern Wyoming. Water-bearing properties of the geologic units are summarized. The hydrogeologic map illustrates the distribution of wells in the different units and gives basic data on the yields of wells, depth of wells, depth...
Water resources data for South Carolina, water year 1975
Water Resources Division, U.S. Geological Survey
1976, Water Data Report SC-75-1
Water resources data for the 1975 water year for South Carolina consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels in wells. This report contains discharge records for 56 gaging stations; stage only records for 4 gaging stations;...
Laboratory hydraulic calibration of the Helley-Smith bedload sediment sampler
Leroy Druffel, W. W. Emmett, V.R. Schneider, J. V. Skinner
1976, Open-File Report 76-752
The Helley-Smith bedload sampler operates on a pressure-difference principle and consists of an expanding nozzle, nylon-mesh sample bag , and external components for structural integrity and stability under flow conditions. The Helley-Smith bedload sampler has a hydraulic efficiency, the ratio of the mean velocity in the sampler nozzle to the...
Geological Survey and selected U.S. Bureau of Mines and Alaska Division of Geological and Geophysical Surveys reports and maps on Alaska released during 1975, indexed by quadrangle
Edward Huntington Cobb
1976, Open-File Report 76-332
All Geological Survey reports and maps on Alaska published or released to open files during 1975 are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 3). Also listed are U.S. Bureau of Mines reports on the geology and mineral resources of Alaska,...
Hard rock uranium potential in Alaska
Thomas P. Miller
1976, Open-File Report 76-246
Discussing the potential of "hardrock" (i.e., non-sedimentary type) uranium deposits in a 586,000 mi2 portion of the North America Cordillera is a difficult task compounded by the fact that the remoteness of much of the region and the logistical difficulties have resulted in only reconnaissance geologic information being available for...
Ground-water levels in Wyoming, 1975
Wilbur C. Ballance, Pamela B. Freudenthal
1976, Open-File Report 76-598
Ground-water levels are measured periodically in a network of about 260 observation wells in Wyoming to record changes in ground-water storage. The areas of water-level observation are mostly where ground water is used in large quantities for irrigation or municipal purposes. This report contains maps showing location of observation wells...
