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...
A gamma-ray absorption method for the determination of uranium in ores
Alfred F. Hoyte
1957, Open-File Report 57-55
Current radioactivity methods used for the determination of uranium in ores are based on the assumption that secular equilibrium exists between the daughter products. Eichholz has developed a method which is claimed to be independent of the degree of equilibrium, but it has been found to be inadequate when used...
Geology of possible petroleum provinces in Alaska
Don John Miller, Thomas G. Payne, George Gryc
1957, Open-File Report 57-72
The history of petroleum exploration in Alaska and the geology of possible petroleum provinces in Alaska are reviewed. Maps showing Alaska's major Mesozoic and Tertiary tectonic elements, possible petroleum provinces, and indications of petrol, are included in this report. Annotated references in Geological Survey publications relating to petroleum and oil...
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...
The deep channel and alluvial deposits of the Ohio Valley in Kentucky
Eugene H. Walker
1957, Water Supply Paper 1411
The alluvial deposits of Pleistocene age in the Ohio Valley form a ground-water reservoir of large storage capacity and yield. In this region it is the only source of large supplies of water that are both cool and of good quality the year round. The reservoir is heavily drawn upon,...
Preliminary survey of the saline-water resources of the United States
Robert A. Krieger, J.L. Hatchett, J. L. Poole
1957, Water Supply Paper 1374
Basic hydrologic data available in the field offices of the U. S. Geological Survey and reports issued by the Survey furnish evidence that saline water (defined in this report as water containing more than 1,000 parts per million of dissolved solids) is available under diverse geologic and hydrologic conditions throughout...
