Geology and pegmatites of part of the Fourmile area, Custer County, South Dakota
A.J. Lang Jr., J. A. Redden
1952, Trace Elements Investigations 155
The Fourmile area, Custer County, S. Dak., is in pre-Cambrian metamorphic rocks that surround the granitic core of the Black Hills. The area is on the upright limb of an overturned anticline that plunges about 30° S. 10° E. Three new formations of metamorphic rocks are described that have a total...
Ground water in the Gila River Basin and adjacent areas, Arizona: a summary
Leonard Cameron Halpenny
1952, Open-File Report 172
This report is a resume' of the principal facts collected by the Geological Survey in the period 1890-1952 about the ground-water resources of the Gila River basin and certain other areas in Arizona. Since 1939 the Geological Survey has been making ground-water investigations on a continuing basis in cooperation with...
Stratigraphy of the outcropping formations in southern Florida
Melvin Carroll Schroeder, Nevin Douglas Hoy
1952, Conference Paper, A summary of the geology of Florida and a guidebook to the Cenozoic exposures of a portion of the State
The geology of southern Florida, except for the Pliocene deposits, is not widely known among geologists and paleontologists. The popular concept is that there are very few outcrops in this part of the State. It is true that there are very few natural exposures, but the dredging of rivers and...
Results of exploration at Lost Creek schroeckingerite deposit, Sweetwater County, Wyoming
Douglas M. Sheridan, John T. Collier, Richard S. Sears
1952, Trace Elements Memorandum 288
The U. S. Geological Survey, on behalf of the Atomic Energy Commission, from July 1951 to February 1952, explored the Lost Creek schroeckingerite deposit, Sweetwater County, Wyoming, by means of auger- drilling, trenching, and bucket-drilling. This report presents an estimate of the inferred ore reserves obtained during this exploration. The inferred reserves are presented under...
Preliminary report on diamond-drill exploration on Outlaw Mesa, Mesa County, Colorado
George K. Brasher
1952, Trace Elements Memorandum 295
Outlaw Mesa is northeast of the Dolores River, about 10 miles southeast of Gateway, Mesa County, Colo. It is an oval-shaped area of about 17 square miles lying mostly within T. 50 N., R. 17 W«, and T. 50 No, R. 18 W., New Mexico principal meridian. The area is accessible by three unimproved...
Preliminary summary of reconnaissance for uranium on the Seward Peninsula, Alaska, During 1951
M.G. White, W.S. West
1952, Trace Elements Memorandum 322
Reconnaissance examinations for uranium were made at nine localities in the York, Nome, and Koyuk districts of the Seward Peninsula, Alaska, during .the 1951 field season. In addition carborne radiometric traverses were made of four roads in the Nome and Council districts. Only at Brooks Mountain in the York district are uranium-bearing deposits that required...
Cyclic fluctuations of water level as a basis for determining aquifer transmissibility
John G. Ferris
1952, Report
In coastal areas, wells near bodies of tidal water frequently exhibit sinusoidal fluctuations of water level, in response to periodic changes of tidewater stage.  Inland, the regulation of a surface reservoir often produces correlative changes of ground-water stage in wells adjacent either to the reservoir or to its attendant stream....
Geophysical observations in parts of the Grants District, McKinley County, New Mexico
Kenneth L. Cook, Calvin K. Moss
1952, Trace Elements Investigations 244
Geophysical observations near Haystack Mesa in the Grants district, McKinley County, New Mexico, had the dual objective of investigating the unusual occurrence of negative aeromagnetic anomalies in close association with airborne radioactivity anomalies, and of investigating other geophysical methods which might assist directly or indirectly in the search for uranium ores in the Grants district....
