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.

From introduction: This report summarizes the results of diamond-drill and wagon-drill exploration by the U. S. Geological Survey in the Yellow Cat area from October 9, 1951, to May 22, 1952. The Yellow Cat area is about 10 miles southeast of Thompsons, Grand County, Utah. It is accessable by two graded roads which leave U. S. Highway 50 at points 5 miles east of Thompsons and 7 miles west of Cisco, Utah. A sampling plant and purchasing depot, belonging to the United States Vanadium Co., is at Thompsons. The explored ground includes about 8 square miles principally in T. 22 S., R. 22 E., and the northern part of T. 23 S., R. 22 E., Salt Lake meridian (fig. 1). Altitudes in the area range from about 4, 600 feet to 5, 100 feet (datum is assumed but is approximately correct), and the relief is moderate.

From abstract: Uranium minerals and radioactivity anomalies occur in many silver lead veins and chalcedony veins and vein zones in the Boulder batholith of southwestern Montana.

The following report summarizes briefly current knowledge of the association of uranium with petroleum and asphalts and presents analytical data compiled during the course of investigations by the U.S. Geological Survey on behalf of the Division of Raw Materials, U.S. Atomic Energy Commission. The primary concern of this paper is focused on uranium and petroleum and natural asphalts.

Purpose and scope: This report is intended to identify many of the causes of saline-water intrusion into freshwater aquifers in Lee County, and to describe some of the effects of the intrusion on ground-water quality. Particular emphasis is placed on saline-water intrusion as related to the construction, operation, and maintenance of wells drilled primarily for water-supply, and to the plugging of wells that are no longer used.

The following report provides information and results of an investigation on heavy mineral concentrates available in the placer deposits of North Carolina during the summer of 1946.

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.
