Abstract: A radiometric reconnaissance, using a portable beta-gamma survey meter, of some geologic formations ranging in age from Cambrian to Cretaceous, and springs in southeastern Idaho, western Wyoming, and northern Utah, has shown that none of them are sufficiently radioactive to warrant further examination of them in the area.

Report discussing investigation of the relation of uranium and phosphate in the Phosphoria formation and its close stratigraphic equivalents.

Report documenting the suitability of Wyoming and Idaho for plant locations to produce synthetic liquid fuels, based on raw materials, water sources, and local interest.

From introduction: The reconnaissance was made during the summer of 1951 by two field parties: (1) a reconnaissance in parts of Oklahoma, Texas, New Mexico, and Arizona by Russell Gibson, and (2) Geological Survey reconnaissance in parts of New Mexico,.Colorado, Utah, Idaho, and Wyoming (by the writers), the results of which are summarized in this report.

Report containing abstracts of some stratigraphic sections of the Phosphoria formation in southeastern Idaho.

From transmittal letter: This report contains the results of radiometric examinations of 39 mines and prospects, and a detailed description of the properties examined.

Report discussing a radiometric examination that took place in 1950 to determine the grade, reserves, and mode of occurrence of uranium and thorium in east-central Idaho and south-western Montana.

From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

Report discussing an investigation of copper deposits in sandstone that were believed to be possibly uraniferous, and uraniferous asphaltite deposits.

This report follows an investigation of a cargo truck found contaminated by various radioactive material on a routine trip from Arco, Idaho to the Hanford plant on May 8, 1952. The report analyzes the truck's route in an attempt to find the location of the contaminating region.

Geologic maps and structure sections of the Johnson Creek Quadrangle in Caribou County, Idaho. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report describing the phosphorite deposits of the western United States with the objective of outlining features that are common to both the Kara Tau phosphorite deposits of Russia and the western United States deposits in an effort to define their origin.

Abstract: During parts of July, August, and September 1951, a reconnaissance was conducted in parts of Colorado, Wyoming, Utah, and Idaho in search of new deposits of uranium-bearing carbonaceous rocks. One significant uranium occurrence was found, the Fall Creek deposit, Bonneville County, Idaho. Several additional localities were discovered that contain uranium in concentrations many times that normally found in carbonaceous rocks.

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 Commission.

Report discussing a study aimed at mapping out stratigraphic sections of the Permian Phosphoria formation in order to locate phosphate beds.

From abstract: Uranium-bearing carbonaceous shale and lignite beds are exposed in the Goose Creek district of southern Cassia County, Idaho. The district includes about 150 square miles in Tps. 14 to 16 So, Rs, 20 to 22 E., Boise meridian.

From introduction: The Bear Valley district is situated in southwestern Idaho, in the drainage of the Middle Fork of the Salmon River (see fig. 1). The placer deposits were drilled by the U. S. Bureau of Mines in 1951 and 1952 to determine their content of monazite and "radioactive black minerals" (here referred to loosely as "radioactive blacks"). The purpose of the study outlined here was to provide a geologic background for an understanding of the origin and distribution of the placer minerals.

From introduction: This report summarizes the results of detailed mapping and sampling completed during 1952 with particular reference to an area of about 60 square miles in T. 16 S. , R. 21 E. , Cassia County, Idaho, and parts of adjacent townships in Idaho, Utah, and Nevada. It supplements an earlier report based on reconnaissance stttdies in the Goose Creek district in 1951 (Hail and Gill, 1953).

Report of investigations issued by the U.S. Bureau of Mines on the Hermada antimony deposit in southwestern Idaho. The investigations included trenching and drilling. The report contains maps of the area, and tables of data.

From abstract: The Mineral Hill monazite deposits, 3 to 5 miles northeast of the town of Shoup, Lemhi County, Idaho, were investigated by the U. S. Geological Survey in July 1952. The deposits are replacement veins and lenses along shears in a pendant, principally of pre-Cambrian biotite gniess, about 4 to 5 miles in size and enclosed by granite of the Idaho batholith. The veins consist predominantly of calcite, monazite, and allanite, and contain minor quantities of barite, magnetite, rutile, and apatite.

Report discussing an investigation of the Centennial Range of Montana and Idaho, and the phosphate deposits of this area. Information on the geology of the area and deposits are given as well as information regarding the quality and location of phosphate deposits.

A preliminary report on the geology of the phosphate deposits located in the Centennial Range in Montana and Idaho.

The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Report discussing a reconnaissance for uranium-bearing carbonaceous rocks during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. From Abstract: "Uranium in small amounts occurs in several of the areas examined, but no deposits were found that might have commercial possibilities."
