Thorium investigations, 1950-52, Wet Mountains, Colorado
R.A. Christman, A. M. Heyman, L. F. Dellwig, G. B. Gott
1953, Trace Elements Investigations 250
The Wet Mountain thorium district was discovered in 1950 by members of the U.S. Geological Survey during reconnaissance investigations for uranium made on the behalf of the Atomic Energy Commission The size of this new district is incompletely known, but the deposits found to date are in an area 20...
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
1953, Trace Elements Investigations 345
Uranium minerals were discovered in the Pumpkin Buttes area Campbell and Johnson Counties 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 with abnormally high radioactivity were found uranium minerals are...
Geology of carnotite-bearing sandstone in the Uravan and Gateway districts, Montrose and Mesa counties, Colorado, and Grand County, Utah
E. J. McKay
1953, Trace Elements Investigations 283
Most of the caraotite deposits in the Uravan and Gateway mining districts ate in the persistent upper sandstone stratum of the Salt Wash sandstone member of the Morrison formation, Areas In which this stratum is predominantly lenticular have been delimited from areas in which this stratum is predominantly nonlenticularar. Ground...
Uranium-bearing carbonaceous shale and lignite in the Goose Creek district, Cassia County, Idaho, Boxelder County, Utah and Elko County, Nevada
William Jameson Mapel, William James Hail
1953, Trace Elements Investigations 339
The Goose Creek district includes about 260 miles in southern Cassia County, Idaho, and adjacent parts of Boxelder County, Utah, and Elko County Nev.  The-area comprises the northern and central parts of an intermontane basin drained by northward-flowing Goose Creek and its tributaries. An essentially conformable sequence of fluviatile, lacustrine, and...
Montroseite, a new vanadium oxide from the Colorado plateaus
Alice D. Weeks, Evelyn A. Cisney, Alexander M. Sherwood
1953, Trace Elements Investigations 335
Montroseite, a new vanadium mineral named from Montrose County, Colorado, has been found in four mines in western Colorado and in two mines in eastern Utah. It is black, opaque, submetallic, and occurs in microscopic bladed crystals of the orthorhombic dipyramidal class. The axial ratio is a:b:c = 0.509:1:0.310, the...
Airborne radioactivity surveys for phosphate in Florida
Robert M. Moxham
1953, Trace Elements Investigations 387
Airborne radioactivity surveys totalling 5,600 traverse miles were made in ten areas in Florida, which were thought to be geologically favorable for the occurrence of uraniferous phosphate deposits. Abnormal radioactivity was recorded in eight of the ten areas surveyed. The anomalies are located in Bradford, Clay, Columbia, DeSoto, Dixie, Lake,...
Reconnaissance for radioactive deposits in the Nixon Fork mining district, Medfra Quadrangle, central Alaska, 1949
Max G. White, John M. Stevens
1953, Trace Elements Investigations 75
Reconnaissance for radioactive deposits in the Nixon Fork mining district, Medfra quadrangle, central Alaska, in 1949 disclosed the occurrence of allanite in sampled containing as much as 0.05 percent equivalent uranium from the dump of the Whalen mine; the presence of radioactive parisite (a rare-earth fluocarbonate) in a highly altered...
