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.

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.

From introduction: This report briefly describes the geologic setting of the Capitol Reef area, uranium deposits, prospecting guides, and plans for continuation of this investigation.

Abstract: Uranium-bearing coal and carbonaceous shale .of the Rio Bonito formation of Pennsylvanian age have been found in the States of Sao Paulo, Santa Catarina, and Rio Grande do Sul, Brazil. The uranium oxide content of the samples collected in the State of Sao Paulo ranges from 0.001 percent to 0.082 percent. The samples collected in Santa Catarina averaged about 0.002 percent uranium oxide; those collected in Rio Grande do Sul, about 0.003 percent uranium oxide. Since the field and laboratory investigations are still in their initial stages, only raw data on the radioactivity and uranium content of Brazilian coals are given in this report.

From abstract: The Thomas Range fluorite district, on Spor's Mountain in the western part of the Thomas Range, Juab County, Utah, is approximately 6 miles long and 2 miles wide, and contains almost no unclaimed land. The fluorite production of the district, since its discovery in 1943, has been 35,700 short tons. It was obtained from 12 different ore bodies on eight different properties. G. P. Spor, Ray Spor, and Chad Spor; Albert Willden and Earl Willden; T. A. Claridge; and W. E. Black and F. B. Chesley were the only groups producing fluorite in the district in August 1950.

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.

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 results presented in this preliminary report are principally concerned with the ground motion caused by seven underground nuclear explosions (table 1) in the bedded tuff of the Oak Spring formation in Area 12. Ground motions were recorded at stations as close as 5 kilometers and as far as 300 kilometers from the explosions (fig 1 and table 2). The results for the Bianca and especially the Evans explosion are meager because the first was accompanied by a Test Site-wide moznentary power failure and because the yield of the second was so far below the anticipated yield that uncertain results were obtained. Ground motions caused by most of the air explosions in Operations Plumbbob and Hadtack - Phase 2 were recorded and have been partly analyzed. Results are presented in this report only where they relate significantly to analysis of the underground explosions. The effects of most of the small underground explosions in Area 3 (center of Yucca Flat) that had significant yields were also recorded. The results have not yet been interpreted.

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 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.

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

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 introduction: "This report summarizes the research work of the Trace Elements Section, Geochemistry and Petrology Branch, from the organization of the Section in April 1948 to December 31, 1950." Investigation of radioactive materials and investigation of methods for analysis of radioactive materials is included.

Report discussing the characteristics and locations of radioactive carbonaceous and bituminous shales in the United States.

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."

"The primary purpose of this report is to present data pertaining to the occurrence, distribution, and geologic environment of deposits of radioactive minerals in California. A secondary purpose is to summarize the information available on occurrences in California and to present a brief description of each radioactive locality that was known prior to 1953."
