Reconnaissance for radioactive deposits in east-central Alaska, 1949
Helmuth Wedow, M.G. White
1954, Circular 335
In the summer of 1949, several mines and prospects in the Fairbanks and Livengood quadrangles, east-central Alaska, were examined for the possible presence of radioactive materials. Also tested were metamorphic and sedimentary rocks of pre-Cambrian and Paleozoic age crossed by the Elliott Highway, which extends from Fox, near Fairbanks, northwestward...
Summary of investigations of uranium deposits in the Pumpkin Buttes area, Johnson and Campbell Counties, Wyoming
Max L. Troyer, Edward J. McKay, Paul E. Soister, Stewart R. Wallace
1954, Circular 338
Uranium minerals were discovered in the Pumpkin Buttes area, Campbell and Johnson Counties, Wyo., by the U. S. Geological Survey in October 1951. From June to November 1952, an area of about 750 square miles was examined for uranium deposits, and 211 localities having abnormally high radioactivity were found; uranium...
Floods of November-December 1950 in western Nevada
J. V. B. Wells
1954, Water Supply Paper 1137-H
Record-breaking floods in the Walker, Carson, and Truckee River basins during November and December 1950 resulted from a rapid sequence of storms and unseasonably high temperatures that melted most of the early snow cover. During the period November 13 to December 8, 1950, total precipitation ranged from about 5 inches...
Geology of the Eureka pegmatite, Pennington County, South Dakota
Roy Eldon Roadifer
1954, Open-File Report 54-256
The Eureka Pegmatite, two miles southeast of Keystone, Pennington County, South Dakota, is a small but possibly valuable zoned body containing more than 85,000 tons of coarse-grained granite-pegmatite rock.The mica in the pegmatite is probably not of any great importance, but the potash feldspar and beryl may comprise a considerable...
Localization of uranium minerals in channel sediments at the base of the Shinarump conglomerate, Monument Valley, Arizona
I. J. Witkind
1954, Trace Elements Investigations 340
During the summers of 1951 and 1952 the U.S. Geological Survey mapped the geology and uranium deposits in three 15-minute quadrangles on the Navajo Indian Reservation in Apache and Navajo Counties, northeastern Arizona. Exposed sedimentary rocks range in age from the Halgaito tongue of the Cutler formation (Permian) to the Salt Wash...
Thorium and rare earth minerals in the Powderhorn district, Gunnison County, Colorado
Jerry C. Olson, Stewart R. Wallace
1954, Trace Elements Investigations 353
Thorium has been found since 1949 in at least 33 deposits in an area 6 miles wide and 20 miles long in the Powderhorn district, Gunnison County, Colo. The district is composed largely of pre-Jurassic metamorphic and igneous rocks, which are chiefly if not entirely pre-Cambrian in age. The metamorphic...
The quality and character of Pacific Northwest waters
Herbert A. Swenson
1954, Report
This paper is a general discussion of the quality and chemical character of surface and ground waters in the Pacific Northwest as shown by the available data. Previous quality of water studies reported in the literature are reviewed. The composition of natural waters is considered as to the source and...
