Geology of the Limestone Hills, Broadwater County, Montana
Edward Thompson Ruppel
1950, Open-File Report 50-14
The Limestone Hills, a natural topographic unit having an area of about 16 square miles, are situated a few miles west and southwest of Townsend, Broadwater County, Montana. They are composed of pre-Cambrian, Paleozoic, and Mesozoic sedimentary rocks i...
Coal resources of New Mexico
Charles Brian Read, R. T. Duffner, G. H. Wood, A.D. Zapp
1950, Circular 89
A study of water quality degradation due to brine contamination was made in an area of about 1,700 sq mi in east-central Oklahoma. The study area coincides in part with the outcrop of the Vamoosa-Ada aquifer of Pennsylvanian age. Water samples collected from 180 wells completed in the Vamoosa-Ada aquifer...
Trace elements reconnaissance in the Jakolof Bay area, southern Alaska
Robert M. Moxham, Arthur E. Nelson
1950, Trace Elements Investigations 74-A
As a result of inquiries by prospectors in 1948 concerning radioactive ores in the vicinity of Jakolof Bay on the Kenai Peninsula in southern Alaska, the Geological Survey conducted a brief investigation during 1949. No radioactive material was found. Possibly a chromite stockpile in this locality was mistaken for pitchblende....
Short routine direct method for the fluorimetric determination of uranium in phosphate rocks
F. S. Grimaldi, Norma S. Guttag
1950, Trace Elements Investigations 134
A short routine direct fluorimetric procedure for the determination of up to 0.06 percent uranium in phosphate ricks is described. The procedure employs a simple acid leach for preparing the solution, and the uranium is determined directly on a 1.8-mg aliquot. The results obtained by using this simply procedure on...
Techniques used in mine-water problems of the east Tennessee zinc district
Deane Frederick Kent
1950, Circular 71
A study of ground water as related to mining in cavernous limestones and dolomites in eastern Tennessee was made in 1946 by the U. S. Geological Survey. Surface and subsurface mapping indicated the geologic control of underground channels. Several methods of tracing water were tried and new techniques in using...
A glossary of uranium- and thorium-bearing minerals
Judith Weiss Frondel, Michael Fleischer
1950, Circular 74
During 1980, an estimated 121 million gallons of water per day was pumped in a 26-county area in east-central Georgia from sand aquifers of Paleocene and Late Cretaceous age. Maximum withdrawals were at the kaolin mining and processing centers in Twiggs, Wilkinson, and Washington Counties, where water levels have declined...
