Middle Tertiary plutonism in the Santa Catalina and Tortolita Mountains, Arizona
S.C. Creasey, Norman G. Banks, R. P. Ashley, Ted G. Theodore
1976, Open-File Report 76-262
Recent reconnaissance geologic mapping in the Santa Catalina and Tortolita Mountains of southeastern Arizona, supplemented by new and published potassium-argon and fission-track ages, suggests that a large middle Tertiary (about 25 m.y.) composite batholith crops out extensively in both mountains. More than two-thirds of the batholith and the contiguous wallrocks...
Map of coal-mining features, Allegheny County, Pennsylvania
W.E. Davies, J. S. Pomeroy, W. R. Kohl
1976, Miscellaneous Field Studies Map 685-C
This map is one result of a series of studies sponsored by the Appalachian Regional Commission as part of a larger U.S. Geological Survey program of environmental analysis of a part of southwestern Pennsylvania. The map summarizes surface features resulting from coal mining. The distribution of surface features is largely...
Limnological survey of Sacony Creek Basin, Berks County, Pennsylvania
James L. Barker, Kenneth P. Kulp
1976, Water-Resources Investigations Report 76-84
Samples of water, fish and benthic macroinvertabrates collected at 10 sampling stations over a 10-month period indicate that Sacony Creek and its major tributaries contain water of good to excellent quality. The waters were found to be free of excessive quantities of dissolved nutrients, oxidizable matter, and fecal coliform bacteria. (p>Fish...
Water resources data for Nevada, water year 1975
Water Resources Division, U.S. Geological Survey
1976, Water Data Report NV-75-1
Water resources data for the 1975 water year for Nevada consist of records of discharge and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels in wells. This report contains discharge records for 120 gaging stations; stage and contents for 21 lakes and...
Mineral resources of Elko County, Nevada
Roscoe Maurice Smith
1976, Open-File Report 76-56
Of the 66 named mining districts in Elko County, 56 have been productive of one or more of 19 different commodities: 11 metals--copper, gold, silver, lead, zinc, mercury, tungsten, manganese, iron, uranium, and antimony; 8 nonmetals--sand and gravel, stone, barite, diatomite, gems, oil shale, volcanic ash, and clay. In addition...
Regional appraisal of the Wilcox Group in Texas for subsurface storage of fluid wastes: Part 1: Geology
Paul Hastings Jones, P. R. Stevens, J. B. Wasselman, R. H. Wallace Jr.
1976, Open-File Report 76-394
Sandy beds of the Wilcox Group in Texas are underlain and overlain by clays of the Midway and Claiborne Groups. The Wilcox is divided by a persistent shale wedge. Contrasting delta systems described as high-constructive and high-destructive exist in the divisions. Merged high constructive deltas characterize the lower, while the...
Lakes Marion-Moultrie stream system investigation, South Carolina : Part II-Simulation Studies
H.H. Jeffcoat, M.E. Jennings, D.L. Collins, J.O. Shearman
1976, Water-Resources Investigations Report 76-11
A stream-reservoir model was developed to simulate the operation of the Lakes Marion-Moultrie, South Carolina, reservoir system. The reservoir system is operated under the assumption of a 3-day prior knowledge of inflows. This information is attainable from the ooperational reservoir-inflow forecasting model developed in the Part I report. The model,...
Mean annual runoff in the upper Ohio River basin, 1941-70, and its historic variation
Robert M. Beall
1976, Open-File Report 76-384
A map of the Ohio River basin above the Muskingum River shows patterns of mean annual runoff for the climatologic and hydrologic reference period, 1941-70. The primary data base consisted of 98 long-term gaging-station records collected within this 27,300-square-mile headwater area of the Ohio River basin. Supplemental information was derived...
