The Model VI transmission fluorimeter for the determination of uranium
Charles Alvin Kinser
1954, Circular 330
An improved transmission fluorimeter (Model VI) for use in the determination of uranium consists of a line-operated, low-voltage d-c supply, powering a small 3-watt ultraviolet lamp as a source of long wavelength ultraviolet radiation; a Model V phototube housing and. fluorimeter head containing the sample holder, shutter, and primary and...
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...
Beryllium resources of the tin-spodumene belt, North Carolina
Wallace R. Griffitts
1954, Circular 309
Pegmatite dikes in the tin-spodumene belt of North and South Carolina uniformly contain about 0.05 percent BeO. The most abundant minerals in the pegmatite contain from 0. 0001 to 0.01 percent BeO. Beryl, having 12.0 to 12.3 percent BeO, is the only beryllium-rich mineral and contains more than 80 percent...
Airborne radioactivity surveys for phosphate in Florida
Robert M. Moxham
1954, Circular 230
Airborne radioactivity surveys totaling 5, 600 traverse miles were made in 10 areas in Florida, which were thought to be geologically favorable for deposits of uraniferous phosphate. Abnormal radioactivity was recorded in 8 of the 10 areas surveyed. The anomalies are located in Bradford, Clay, Columbia, DeSoto, Dixie, Lake, Marion,...
Stripping-coal deposits on lower Lignite Creek, Nenana coal field, Alaska
Clyde Wahrhaftig, Joseph H. Birman
1954, Circular 310
Stripping-coal reserves in an area of about 9.4 square miles extending from the Nenana River about 6 miles up the valley of Lignite Creek are estimated to amount to about 95, 000, 000 tons. The stripping-coal reserves are located in the lower and middle members of the Tertiary coal-bearing formation....
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...
Water resources of the Pittsburgh area, Pennsylvania
Max Noecker, D.W. Greenman, N.H. Beamer
1954, Circular 315
The per capita use of water in the Pittsburgh area in 1951 was 2, 000 gallons per day fgpd) or twice the per capita use in Pennsylvania as a whole. An average of about 3, 040 million gallons of water was withdrawn from the streams and from the ground each...
First Fourteen Years of Lake Mead
Harold E. Thomas
1954, Circular 346
This circular summarizes the results of recent studies of Lake Mead and its environs. Area-capacity tables, prepared on the basis of a hydrographic survey of the lake in 1948-49, show that the capacity of the reservoir was reduced 4.9 percent during the first 14 years after Hoover Dam was completed,...
A reconnaissance for uranium in New Mexico, 1953
Roy Lee Griggs
1954, Circular 354
In the fall of 1953 a reconnaissance for uranium was made in the Datil area of west-central New Mexico, and in the Cerrillos mining district, the Glorieta and Tecolote districts, and the Las Vegas and Colfax sill areas of north-central to northeastern New Mexico. Traces of radioactive materials were detected...
