Preliminary report on the Comet area, Jefferson County, Montana
George Earle Becraft
1952, Trace Elements Investigations 282
Several radioactivity anomalies and a few specimens of sooty pitchblende and other uranium minerals have been found on the mine dumps of formerly productive base-and precious-metal mines along the Comet-Gray Eagle shear zone in the Comet area in southwestern Montana. The shear zone is from 50 to 200 feet wide...
Distribution of ore deposits and spectrographic analyses of some rocks and ores on the Colorado Plateau
Leonard Benjamin Riley, Eugene Merle Shoemaker
1952, Trace Elements Investigations 278
The geographic pattern of known igneous rocks and ore deposits on the Colorado Plateau suggests a zonal arrangement of several types of ore deposits around centers of igneous activity. Spectrographic analyses of rocks and ores on the Plateau have been obtained in an effort to determine the distribution of elements and...
Results of diamond drilling and geologic investigation of the Shirley May (Garo) uranium deposit, Park County, Colorado
Verl Richard Wilmarth, L.E. Smith
1952, Trace Elements Investigations 277
The Shirley May (Garo) uranium deposit near Garo, Park County, Colo., consists of tyuyamunite and carnotite that occur as disseminations and as fracture fillings in three beds of medium- to coarse-grained sandstone. The sandstones are in the Maroon formation of Permian age. This deposit was explored by means of 12 core-drill holes, totalling...
Minor elements in Arkansas bauxite
M. Gordon Jr. , K. J. Murata
1952, Economic Geology (47) 169-179
A study of the minor elements in Arkansas bauxite has revealed some striking relationships between their concentration in the parent nepheline syenite rocks as compared with their concentration in the bauxite. The ratios of concentration, in general, follow a pattern predicted by Gold-schmidt (3),2 based upon the ionic radius and ionic charge of each element present. In the Arkansas deposits, Mg, Ca, Ba, La, and Sr were depleted during...
Trace elements reconnaissance investigations in New Mexico and adjoining states in 1951
George O. Bachman, Charles B. Read
1952, Trace Elements Memorandum 443
In the summer and fall of 1951, a reconnaissance search was made in New Mexico and adjacent states for uranium in coal and carbonaceous shale, chiefly of Mesozoic age, and black marine shale of Paleozoic age. Tertiary volcanic rocks, considered to be a possible source for uranium in the...
Geology of the area adjacent to the Free Enterprise uranium-silver Mine, Boulder District, Jefferson County, Montana
W.A. Roberts, A. J. Gude III
1952, Trace Elements Memorandum 140
Uranium minerals.occur in pods associated with cryptocrystalline silica, silver minerals, and scattered sulfide mineral grains in a hydrothermal vein that cuts quartz monzonite and alaskite at the Free Enterprise mine, 2 miles west of Boulder, Mont. The Free Enterprise vein is one of many silicified reef-like structures in this area,...
Topical index and bibliography of U.S. Geological Survey Trace Elements and related reports
Diane Curtis, Shirley S. Houser
1952, Trace Elements Investigations 301
Part 1, the topical index, lists the titles of reports prepared from 1941 to December 1952, in conjunction with the Geological Survey's program of uranium and other elements of related interest. It includes not only completed Trace Elements reports and those now in preparation, but also Survey publications, publications by...
Airborne radioactivity surveys in the Mojave Desert region, Kern, Riverside, and San Bernardino Counties, California
Robert M. Moxham
1952, Trace Elements Memorandum 360
Airborne radioactivity surveys in the Mojave Desert region Kern, Riverside, and Bernardino counties were made in five areas recommended as favorable for the occurrence of radioactive raw materials: (1) Rock Corral area, San Bernardino County. (2) Searles Station area, Kern county. (3) Soledad area, Kern County. (4) White Tank area,...
Numerical list of U.S. Geological Survey trace elements reports to September 15, 1952
Jane H. Wallace, Virginia K. Blatcher
1952, Trace Elements Investigations 300
This report lists in numerical order U.S. Geological Survey Trace Elements Investigations and Memorandum Reports and supersedes a similar report issued in January 1952 (TEI-202). This report contains lists not only of reports that have been transmitted to the U.S. Atomic Energy Commission, that is, those reports followed by a date,...

Occurrence of uranium-bearing coal, carbonaceous shale, and carbonaceous limestone in the Fall Creek area, Bonneville County, Idaho
James D. Vine, George W. Moore
1952, Trace Elements Memorandum 340
Uraniferous coal, carbonaceous shale, and carbonaceous limestone occur in the Bear River formation of Upper Crestaceous age at the Fall Creek prospect, in the Fall Creek area, Bonneville County, IDaho. The uranium compounds are believed to have been derived from mildly radioactive silicic volcanic rocks of the Tertiary age...
