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.

Uranium deposits in the precambrian quartz-pebble deposits of the Raft River area in northwestern Utah and southcentral Idaho are examined. A total of 1214 geochemical samples were acquired for the study, particularly 334 water samples, 616 stream sediment samples, and 264 rocks.

This report provides results from a preliminary study to determine rock types and alteration products that are responsible for an observed abundance of radioactive gas at the Trinity Gold Mine in Utah. It includes an overview of the study and the location, description of the methods and general statements, details about the structure, petrography and mineralogy, and a discussion of findings.

From abstract: The subsurface isorad method is an attempt to locate areas favorable for uranium ores by the use of contour maps which show localities having greater radioactivity. The construction of isorad maps entails the measurement of the area under the curve of a gamma-ray logo The figures obtained indicate relative amounts of gamma radiation and are used to locate the isorad contours. This work was started at Temple Mountain in the San Rafael Swell area during the spring of 1952. The purpose of this investigation is to determine the most effective and economic hole spacing for subsurface isorad work.

This report presents preliminary results of ground water, stream sediment, and stream water studies in the Delta and Richfield quadrangles in Utah.

"The purpose of this profile is to summarize the ecological information available for and relevant to stream and riparian habitats of the Great Basin. The Great Basin comprises the northern half of the Basin and Range physiographic province and covers most of Nevada and western Utah and portions of California, Oregon, and Idaho. The entire basin actually consists of numerous subbasins and mountain ranges which present an extremely diverse physical setting" (p. iii).

Partial abstract: "During the summers of 1976, 1977, and 1978, 442 water and 1755 sediment samples were collected from 1801 locations within the 19 400 km2 area of the Moab quadrangle, Utah and Colorado, by private contractors for the Los Alamos Scientific Laboratory. Water samples were collected from streams, springs, and wells; wet and dry sediment samples were collected both from stream channels and from springs. Each water sample was analyzed for 13 elements, including uranium, and each sediment sample was analyzed for 43 elements, including uranium, thorium, and vanadium. All field and analytical data are listed in the appendixes of this report" (p. 1).

Report discussing investigations seeking uranium in deposits of black shale around the geographical areas of the Western States

From introduction: The primary object of this work was to aid prospectors and mining men in finding and exploiting new deposits of uranium-bearing ores in the Colorado Plateau region, particularly of those in the Shinarump and Moss Black members of the Chinle formation.

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 proposed nomenclature of Upper Triassic rocks in southeastern Utah in which two types of strata are lumped together in the Chinle formation and that the Shinarump conglomerate be redefined as the Shinarump member of the Chinle formation.
