Pegmatite geology of the Shelby district, North Carolina
Wallace R. Griffitts
1957, Open-File Report 58-40
The Shelby district is divided into a northwestern and a southeastern province. The rocks in the southeastern province include various units in the Battleground schist formation and the Yorkville granodiorite. Those in the northwestern province include the Carolina gneiss, with its Shelby gneiss member, and the Toluca quartz monzonite. The...
Uraniferous coal and carbonaceous shale in northeast Parana, Brazil
Donald D. Haynes, Charles T. Pierson
1957, Trace Elements Memorandum 1097
Uraniferous coal has been found in northeast Parana, Brazil, in the Rio Bonito formation of Pennsylvanian age. In the majority of coal samples taken the uranium oxide content ranges from 0.005 to 0.030 percent, but selected screened samples have contained as much as 0.445 percent uranium oxide. The sampled thickness...
Construction and use of special drawdown scales for use in prediction of water-level changes throughout heavily pumped areas
C.S. Conover, H.O. Reeder
1957, Open-File Report 57-24
Problem and Proposed Method of Solution Frequently the Theis nonequilibrium formula is use din the quantitative analyses that are part of many-ground-water investigations. The computations associated therewith may become quite involved and tedious, especially when dealing with predictions of the decline of water levels throughout large areas in which there are...
Occurrence of ground water near Ana Springs, Summer Lake Basin, Lake County, Oregon
S. G. Brown
1957, Open-File Report 57-17
Ana Springs are near the north end of Summer Lake Basin, a closed fault-block basin in Lake County Oregon. The water of the springs rises by artesian pressure from lava-rock aquifers through about 150 feet of overlying thinly bedded lake deposits to discharge at the bottom of an impounding reservoir,...
Geology of Gabbs and vicinity, Nye County, Nevada
Charles J. Vitaliano, Eugene Callaghan, Norman J. Silberling
1957, Miscellaneous Field Studies Map 52
The geologic map of Gabbs and vicinity covers approximately 105 square miles of the northwestern part of the Paradise Peak quadrangle. The present report stresses the igneous, metamorphic, and structural geology. The map published at this time shows, (1) the distribution of igneous rocks in the area, (2) the relationship...
Interregional management of ground and surface water
H. E. Thomas
1957, Open-File Report 57-110
I feel that there is not a large gap between what we have and what we need for "management" of the people who must give their assent to any program for management of water resources. We need a "generalist" approach in addition to our specialist approach, to achieve a synthesis...
