Chatanooga shale investigations along the Sequatchie anticline of Tennessee and Alabama
Lynn Glover
1954, Trace Elements Investigations 470
In 1953 the Chattanooga shale in the Sequatchie anticline was tested for its uranium content by seven diamond drill cores. Concurrent with the drilling, geologic field work was done to determine the distribution, thickness, and structural setting of the shale. The results of this investigation indicate that the Chattanooga...
Wet Mountains, Colorado, thorium investigations, 1952-1954

1954, Trace Elements Investigations 354
A 22-square mile tract (McKinley Mountain Area) of pre-Cambrian rocks and veins containing thorium was mapped at the scale of 1:6,000. This tract lies on the west flank of the Wet Mountains, Custer and Fremont Counties, northeast of Westcliffe, Colo. The bedrock is a complexly interlayered sequence of gneisses of metasedimetary...
Appraisal of the accuracy of U.S. Geological Survey ore reserve estimates for uranium-vanadium deposits on the Colorado Plateau
Alfred Lerner Bush, Harold Keith Stager
1954, Trace Elements Investigations 288
The U.S. Geological Survey has made estimates of the reserves of uranium and vanadium in the carnotite deposits explored by Geological Survey drilling on the Colorado Plateau. This report presents an appraisal of the accuracy of the reserve estimates for deposits in the Uravan mineral belt, the causes of inaccuracy,...
The copper and uranium deposits of the Coyote district, Mora County, New Mexico
C.M. Tschanz, D.C. Laub, G.W. Fuller
1954, Trace Elements Investigations 356
The copper and uranium-vanadium deposits of the Coyote district, Mora County, N. Mec, are confined to the lower 2,000 feet of the Sangre de Gristo formation of Pennsylvanian and Permian age. A narrow belt of deposits in steeply dipping or overturned rocks extends for 7 miles along Coyote Creek south...
Monazite in Atlantic shore-line features
Lincoln Dryden, Glen A. Miller
1954, Trace Elements Investigations 407
This report is a survey of present and potential production of monazite from part of the Maryland-Florida section of the Atlantic Coastal Plain. The part of the Coastal Plain covered here is the outer (shore-ward) half. In this area, all the large heavy-mineral placers so far discovered occur in sand bodies...
