Abstract: San Miguel bench includes about 4 square miles in the southern part of T. 48 N., R. 17 W., New Mexico principal meridian, Montrose County, Colorado. Production of carnotite ore from the area has been about 15, 000 short tons having an estimated average graderof 0. 31 percent U3O8,and 1. 6 percent V2 05 Nearly all of the carnotite deposits occur in a single-continuous sandstone bed near the top of the Salt Wash member of the Jurassic Morrison formation. These deposits consist chiefly of sandstone impregnated with uranium- and vanadium-bearing minerals. They are irregular tabular-shaped masses ranging in size from a few short tons to 30, 000 short tons or more of minable carnotite ore. During the period November 27, 1951, to April 17, 1953, the U. S. Geological Survey drilled 309 holes totaling 92, 194 feet on the San Miguel bench. Reserves total about 43, 000 short tons of material 1 foot or more thick and contain 0,.10 percent or more U30 or 1. 0 percent or more V205. Of these reserves 3, 300 short tons occur in private land. These reserves are in ten deposits found by Geological Survey drilling. Potential reserves (reserves based on geologic evidence …

Report discussing the San Miguel bench and the production of carnotite from deposits consisting of sandstone with uranium- and vanadium-bearing minerals.

Report discussing a petrographic study of the uranium ore-producing formations of the Colorado Plateau by means of thin section study, grain-size analyses and the field examination of sedimentary procedures.

From abstract: "In 1953 the Chattanooga shale in the Sequatchie anticline was tested for its uranium content by seven diamond drill cores. Concurrent with the drilling, geologic field work was done to determine the distribution, thickness, and structural setting of the shale." The report contains information regarding location and drainage, geology, the drilling program, subdivisions of the Sequatchie anticline, and unpublished reports.

"The results of an investigation of the Chattanooga shale along the Sequatchie anticline of Tennessee and Alabama are summarized in this report. The project was of an exploratory nature designed to 1) obtain fresh core samples from areas where analyses of outcrop samples showed uranium contents as high or higher than those of the Youngs Bend area in DeKalb County, Tenn.; 2) learn more about the distribution and thickness of the shale in those areas and, if necessary, do some geologic mapping; 3) observe general topographic, drainage, and geologic conditions that would affect the mining of shale."

A report about strata of conglomeratic sandstone which is localized st the base of the Brushy Basin shale member of the Morrison formation of Jurassic Age. These strata are discrete lithologic units which contain sedimentary structures oriented in a prevailing easterly direction.

Report discussing a procedure for determinion of thorium in monazite ores and other ores with diverse composition. This procedure can be used for high and low grade ores.

Abstract: "The thiocyanate method is applied to the determination of uranium in ores after separation by ethyl acetate extraction." Sections are included for prelimnary experiments, and the procedure for the analysis of uranium ores and minerals.

Abstract: A study has been conducted to provide data on the loss of germanium from ashed lignite samples. The lignite samples, of known germanium content, were ashed at various temperatures as high as 1000 °C with varying rates of heating and varying amounts of surface area of the lignites. The results indicate that no germanium was volatilized during the various ignitions.

The following report covers the study of the area described in this report that is part of the White Canyon mining district, San Juan County, Utah. Upon this investigation, uranium deposits were discovered and analyzed.

Report discussing a method for using benzidine to identify altered tuff in sandstone. The method is "practical for field or field laboratory studies associated with stratigraphic correlations, mineral deposit investigations, or paleogeographic interpretations."

From introduction: Under the general supervision of the Health Division of the Los Alamos Scientific Laboratory, the U.S. Geological Survey is participating in geologic and hydrologic studies of the tile field constructed in Jackass Flats in the southwestern part of the Nevada Test Site as related to waste disposal, M. D. Shutler rendered valuable assistance in obtaining and evaluating portions of the data in this report. These investigations were done on behalf of the U.S. Atomic Energy Commission and were supported by the Division of Reactor Development and by the Albuquerque Operations Office.

The following report covers the study of the site adjacent to Campbell Cove on Bodega Head, Sonoma County, California, focusing on questions such as: 1) its position relative to the San Andreas fault zone; 2) the possibility that minor faults, related to the San Andreas fault, might actually pass through the site; and 3) the seismic hazards posed by the nearby San Andreas fault zone.

Introduction: Detailed geologic mine mapping and sampling of the J.J. mine in the Jo dandy area, Montrose County, Colo., were undertaken to study a vanadium-uranium ore body in terms of the physical relationships of ore to host rock, the paragenetic sequence of ore minerals, and the sequential development of an oxidized suite of ore minerals from unoxidized ore.
