Introduction: Geologic studies by the U.S. Geological Survey in support of the U.S. Air Force's Project Pluto in Area 401 of the Nevada Test Site were made on behalf of the U.S. Atomic energy Commission.

From abstract: This report is on the geologic studies in the U12e.07 tunnel for the purpose of determining the structural features, lithographic character, chemical composition, and physical properties of the tuff exposed in the tunnel.

Abstract: Geophysical logs, a summary of contract costs, detailed descriptions of drilling, casing, cementing, and hydraulic testing operations, X-ray mineralogical analyses, physical property analyses, and a detailed lithologic log are presented in the report.

The following report presents a summary of thermochemical data of minerals collected by various contributors.

From introduction: This report details the seismic measurements by the USGS during the pre-Gnome high-explosives tests near Carlsbad, New Mexico.

A report about the absorption spectra of the thallium-dithizone mixed-color system. An analytical procedure based on this system is given which is applicable to pure solutions.

A report which refers to a study that indicated there is a significant correlation between electrical resistivity and the relative favorability for occurrence of ore.

The following report covers a study of the electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau province where it is indicated that there is a significant correlation between electrical resistivity and the relative favorability for occurrence of ore. This report presents the measurements of resistivity trends.

From abstract: This report describes geologic and oceanographic factors relevant to the selection of a site in northwestern Alaska, at which an experimental harbor can be created by the explosion of a nuclear device. Part I describes the results of a preliminary survey of the entire coastal and offshore region between Nome and Point Barrow: Part II consists of a more detailed evaluation of the Cape Thompson-Cape Seppings area; and Part III is a theoretical consideration of the effect of the ocean upon the temperature and distribution of permafrost. The report is based entirely upon the study of published and unpublished reports, field notes, and maps, interviews with the few geologists who have visited the region, and the interpretation of aerial photographs.

From abstract: This report describes the Rainier underground test of September 19, 1957 conducted at the Nevada Test Site with a 1.7 kiloton nuclear device.

The following report covers geological studies on the Capitol Reef area in western Wayne and north-central Garfield Counties, Utah.

Report discussing the geology of the Garo deposit, which is located in the west-central part of Park County, Colorado.

Report outlining detailed information about the geology of the Garo deposit in Colorado, mined for radium, uranium, vanadium, and copper. It specifically discusses the geology related to the various ores, as well as other relevant characteristics.

From abstract: The Rainy Day mine in the Circle Cliffs area, Utah, is developed Dn a long slender pod of uranium ore. Ore is localized in siltstone of the Moenkopi formation of Triassic age, on the south edge of a channel about 3,300 feet wide by 40 feet deep that is filled with sandstone of the Shinarump member of the Chinle formation of Triassic age. Shale of the Chinle rests directly on siltstone of the Moenkopi on either side of the channel.

Report discussing the geology of the Rainy Day uranium mine in Garfield County, Utah. From Introduction: "This report describes the relation of the uranium deposit to the local geology and presents several ore and subore analyses which show similarities between this deposit and those in the Shinarump and Moss Back members of the Chinle formation of the Triassic age."

Abstract: "Monazite placers in the western Piedmont of North and South Carolina were explored by the U. S. Geological Survey in 1951-54 and are estimated to contain at least 53,000 short tons of ThO2 and 4,600 short tons of U3O8. None of these deposits is being mined."

The following report describes a laboratory sample splitter, the slotted cone splitter, designed in in the form of 60[degree] cone.

Report discussing the contact and weathering of the Burro Canyon formation shales and Dakota sandstone as well as other connections of the Burro Canyon formation.

The following report covers measurements of electrical resistivity and dielectric constant that were made on parts of 27 cores from the Morrison formation in the Colorado Plateau uranium province as part of a program to obtain basic data on the physical properties of the rock in and near uranium-mineralized zones.

The following report describes the petrography of uranium-bearing carbonaceous shale and a non-uranium-bearing impure coal from two of the drill cores that were used to explore the underground extent of the east-central part of the Goose Creek district.

From abstract: "The Crevasse Canyon formation and Point Lookout(?) sandstone of Late Cretaceous age and the Baca and Datil formations of Tertiary age were mapped in an area of 168 square miles in the upper Alamosa Creek Valley along the northern edge of the Datil Mountains, Catron County, N. Mex. The investigation was made to determine the potentialities of the area for producing uranium and to learn the geologic controls for the concentration of uranium."

From introduction: The purposes of this paper are to tabulate and discuss the results of a number of complete disequilibrium analyses, to illustrate a proposed classification of disequilibrium patterns, to study these disequilibria as clues to the understanding of the geochemical history of the samples and of the deposits, and to point out some of the difficulties when simply comparing radioactivity and chemical uranium assays for interpreting equilibrium or disequilibrium in samples.
