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.

The following report is the last in a series of periodic reports covering investigations made by the U.S. Geological Survey on behalf of the Divisions of Raw Materials and Research of the U.S. Atomic Energy Commission. The following is a bibliography of Geological Survey publications stemming from investigations on radioactive materials and deposits since 1942.

Report discussing the results of geologic drilling of the land-pebble phosphate district in Florida. Specifically, the general geology, stratigraphy, mineralogy, chemistry, weathering, and economic geology are discussed.

From abstract: Investigations of the land-pebble phosphate deposits of Florida by the Geological Survey began in November 1947. This report presents the computation of reserves of phosphate rock in the northern part of the district.

The following report analyzes the contaminant materials found in glaciers and ice caps.

From introduction: This report contains the results of a preliminary study of limestone deposits in the United States and Alaska for the purpose of selecting those deposits of sufficient size, relief, and purity in which to conduct an underground nuclear test.

From abstract: "This report is a survey of present and potential production of monazite from part of the Maryland-Florida section of the Atlantic Coastal Plain."

Report discussing the geology of uranium deposits located in the King Mountain area, Hueco Mountains area, and other areas of west Texas.

From introduction: This report details Vela Uniform program survey that determined the pre-explosion chemical and physical properties of the tuffs exposed in the tunnel for comparison with similar post-shot geologic data and evaluated these data in terms of predicting the geologic effects of the planned explosion.

Report discussing the investigation of radioactivity in coal beds and associated rocks from the Pottsville, Allegheny, and Conemaugh formations in Beaver, Clearfield, and Jefferson counties, Pennsylvania. The report provides information regarding the procedures used, descriptive geology of the areas, radioactivity data, factors affecting the occurrence of radioactivity, and a summary.

Report discussing the U.S. Geological Survey's investigation for uranium in the Datil area, west-central New Mexico, and in the Cerrillos, Glorieta, and Tecolote districts and the Las Vegas and Colfax Sill areas of north-central to northeastern New Mexico during the fall of 1953. Information regarding the reconnaissance's results is divided by area.

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.

Report discussing beryllium deposits in the form of beryl, helvite, and beryllian idocrase in a small area of the Victorio Mountains of Luna County, New Mexico.

From abstract: This report describes the Chariot test at Ogotoruk Creek that is topographically and geologically well-situated for the construction of an experimental deep-water excavation as proposed by the AEC.

From introduction: This report details the results of geologic investigations in support of Project Chariot.

Abstract: Radioactive zones are present in the upper silty part of the pre-Cambrian Dripping Spring quartzite at the Red Bluff prospect, Gila County, Ariz. The prospect is in the SE 1/4 sec. 31, T. 5 N., R. 14 E., at the southern end of the Sierra Ancha area and 12 miles northeast of Roosevelt Dam. Stratigraphic control of the radioactive zones is indicated by the restriction of the zones to two layers, each about 20 feet thick.The zones are spatially associated in part with a diabase dike that occupies a fault, and in part with a thick diabase sill. The main uranium mineral disseminated through the rock in these zones has not been identified definitely, although minor quantities of secondary uranium minerals were observed. The results of scintillometer traverses and radiometric analyses indicate that the deposits probably contain an average of 0.026 percent uranium. Some black streaks and some fractures contain a higher percentage of uranium, but so far as is known the volume of such material is probably too small to affect the overall grade of the deposits.

Abstract: Uraniferous rock was discovered in the Phillips mine-Camp Smith area in 1953. Precambrian rocks of the Hudson Highlands of the New England physiographic province underlie the area.

Report discussing uranium that was discovered in uraniferous rock in the Phillips mine-Camp Smith area of New York in 1953.

A report discussing and area of 2.5 square miles along the southwest border of the pre-Cambrian granitic rocks complex in the pre-Cambrian core of the Harney Peak region, Black Hills, South Dakota that was mapped to determine the relationship between the granite-pegmatite complex and the pegmatites containing beryl and other industrial minerals. This investigation was part of the U.S. Geological Surveys program for the investigation of domestic beryllium resources and was carried out on behalf of the Atomic Energy Commission.

Abstract: "This bibliography supplements the information on salt published in U.S. Geological Survey Bulletin 1019-J, "Annotated Bibliography and Index Map of Salt Deposits in the United States," by Walter B. Lang, 1957. The supplement contains additional information on the salt deposits of the United States and of foreign countries, as well as data on the composition, chemistry, geologic occurrences, geophysical exploration, distribution, technology, and production of salt. Additional supplements will be issued from time to time to keep information on these subjects current."

Report discussing the uranium deposits located in the Miller Hill area of Carbon County, Wyoming. A stratigraphic description of the area is also given.

Report discussing a preliminary study of limonite sourced from nine localities of different types through Colorado, Utah and Wyoming, in the spring and fall of 1953. This study aimed to establish criteria for differentiating uranium- and thorium-related limonite and limonite not related to uranium or thorium. The report is divided by descriptions of each locality.

A report regarding a preliminary study of radioactive limonite localities in Colorado, Utah, and Wyoming. Concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic energy Commission.

From Introduction: "In the Uravan and Gateway districts, the general character of the bedding in the ore-bearing sandstone and amount of alteration in associated mudstones, and the relation of these to each other, are the features most useful as large-scale guides. This report describes these features and their distribution, as well as some other significant geologic characteristics of the ore-bearing sandstone."
