Report discussing the use of an air concentrator on uraniferous sandstones for producing concentrates with over ten times the amount of uranium as original sandstone. A description of the concentrator, information regarding its operation, results of the concentration, information on the concentrator's applications, and a general summary are included.

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

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

Report discussing a reconnaissance study performed in September and October 1954 of the Bisbee district in Cochise County, Arizona. The purpose of the study was to determine the area's suitability for a detailed study of the relation between uranium and hypogene mineral zoning.

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.

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 a research program on the isotope geology of the uranium and thorium series. From Abstract: "Work is in progress on uranium-lead relationships in uranium ores of the Colorado Plateau region; on uranium-thorium-lead relationships in granite; on geologic variations in the isotopic composition of lead; and on radon and helium in natural gas."

Report discussing the geology and pegmatites of the Fourmile Quadrangle, located on the southwest side of the Black Hills uplift in Custer County, South Dakota. "This report is an abstract of a paper with the same title that is planned for publication as a Geological Survey professional paper."

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."

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.

Glossary of minerals containing uranium and thorium. "In the index there are 325 entries which represent 81 species containing uranium and thorium as major constituents, 39 species containing small amounts of uranium and thorium, 29 species which should be tested for uranium and thorium, and 13 species which have been reported to contain impurities or intergrowths of uranium, thorium, or rare-earth minerals."

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

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: 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 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 results of a geological survey from 1948 to 1950 to determine the mode of occurrence of beryllium in non-pegmatitic rocks and mineral deposits. "The main topics discussed are: uses and properties of beryllium; methods of analysis and mineralogy of beryllium, occurrence of beryllium in igneous, sedimentary, and metamorphic rocks, pyrometasomatic and related deposits, vein deposits, and hot spring deposits; the genesis of beryllium deposits; and a description of the deposits examined."

Report discussing the location, occurrence and chemical character of ground water in the Morrison formation near uranium-vanadium ore mineral deposits. Conclusions are included.

A report discussing the occurrence and chemical character of ground water in the Morrison Formation in Southeastern Colorado and Southeastern Utah.

Report discussing a study regarding the metamictic state of zircon group minerals. This study was aimed at better understanding metamictic alteration. Experimental data and discussion of various metamictic zircons are included.

Report discussing a study on the Central City district and adjoining mining areas to determine the geology and economic importance of the uranium occurrences in the region.

From Introduction: "This report summarizes the practices and results obtained with three dust-collecting machines that were adapted as sample collectors for wagon-drill cuttings."

Report discussing a geological investigation of the age of Colorado Plateau uranium ores using the lead-uranium methods. The objective of the study was to determine whether the uranium deposits in the Shinarump conglomerate are late Triassic and that those in the Morrison formation are late Jurassic, or whether all deposits are late Cretaceous to early Tertiary.
