Selected Papers on Uranium Deposits in the United States

Description: From foreword: The six papers included in this report were prepared in an attempt to summarize briefly, and make available to the public, part of the information concerning uranium deposits that is in unpublished reports of work done by the U. S. Geological Survey under the auspices of the Manhattan Engineer District, and later, the U. S. Atomic Energy Commission.

Progress Report on Geologic Studies in the Capitol Reef Area, Wayne County, Utah

Description: From abstract: During 1951 about 60 square miles of the Capitol Reef area, Wayne County, Utah, the northern end of the Waterpocket Fold, was mapped by plane-table methods on a scale of 1:62, 500. Formations, with an approximate aggregate thickness of 3, 200 feet, range from the Coconino sandstone of Permian age to the Navajo sandstone of Jurassic (?) age. About 35 linear miles of Shinarump conglomerate of Triassic age was examined in detail. Cliffs 900 to 1, 000 feet high form the west face of … more

The Geological Survey's Work on the Geology of Uranium and Thorium Deposits

Description: From abstract: The Geological Survey has been studying the geology of uranium and thorium continuously since 1939, when it began a comprehensive investigation of the vanadium-uranium deposits of the Colorado Plateau. Greatly increased demand for uranium arising from the advent of controlled fission in 1942 resulted in widening of the study in 1944 to include other possible sources and in further expansion on behalf of the U. S. Atomic Energy Commission since 1947. The wide variety of materials… more

Distribution and Origin of Phosphate in the Land-Pebble Phosphate District of Florida

Description: From abstract: The land-pebble phosphate district of Florida is a part of the Gulf Coastal Plain. The geologic formations cropping out in the district are the Miocene Hawthorn, Pliocene Bone Valley, and Pleistocene terrace sands. The Bone Valley formation consists of a lower strongly phosphatic unit and an upper less phosphatic unit. This paper is concerned principally with the lower unit, which contains the bulk of the minable phosphate deposits of the district.

A Semiquantitative Spectrographic Method for the Analysis of Minerals, Rocks, and Ores ([Part] 2)

Description: Abstract: The scope of the semiquantitative spectrographic method for the analysis of minerals, rocks, and ores previously described as determining 55 elements, has now been increased to 68 elements which can be estimated in one exposure of a l0-mg sample. Fluorine, the 69th element, requires a separate exposure for some materials. The method has been used to complete about 185,000 determinations in the past two years. Listed in this report are 336 chemical check analyses that indicate approxim… more

Investigations in the Fall Creek Area, Bonneville County, Idaho, During the 1952 Field Season: A Preliminary Report

Description: Introduction: Field work during the 1952 field season has supplied new data on the areal extent, composition, and estimated reserves of uranium-bearing carbonaceous rocks in the Fall Creek.area, Bonneville County, Idaho. The following is a preliminary report of progress to describe these new data which supplement the information contained in Trace Elements Memorandum Report 340 (Vine and Moore, 1952). This work was done on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commi… more

Uranium-Bearing Copper Deposits in the Coyote Mining District, Mora County, New Mexico

Description: Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Permian and Pennsylvanian age south of Coyote, Mora County, New Mexico. Detailed mapping and sampling of these deposits indicate that they occur in carbonaceous zones in shales and arkosic sand-stones. Samples contain as much as 0.067 percent uranium. A yellow radioactive mineral found in the deposits was identified as metatyuyamunite. All of the samples were collected near the surface a… more

The Uranium Occurrences in the Martha E Prospect, Lawson-Dumont District, Clear Creek County, Colorado

Description: From introduction: The Martha E prospect, in Spring Gulch about three and one-half miles southwest of Idaho Springs, Colo. (fig. 1), is on a claim, originally called the Daisy Freese, which was first prospected by the Stanley Mines. The occurrence of radioactive minerals in the adit was called to the attention of the U. S. Geological Survey in 1950 by the owners of the claim. The Survey's Trace Elements Section Washington Laboratory identified metatorbernite, autunite, and sooty pitchblende.

Preliminary Report on Exploration in the Spud Patch Area, San Miguel County, Colorado

Description: From introduction: From November 1949 to May 1952, the U. S. Geological Survey explored the Spud Patch area by diamond drilling to find carnotite deposits that would make new mines and to appraise the reserves of the area. Previous work and a brief outline of the general geology of the area have been reported (Bell and Icke, 1950; and Bell, 1952).

Progress in Airborne Radioactivity Surveying

Description: From abstract: The objectives in the investigation of airborne radioactivity surveying during fiscal year 1951 were: 1) Establishment of a routine technique of airborne radioactivity surveying -- completed by incorporating those phases of the aeromagnetic surveying technique that were applicable; 2) Development of automatic correction of the radiation measurement for variation in distance from source -- achieved by using the radar altimeter output to modify the output of the counting-rate meter… more
