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.

A report discussing a geologic reconnaissance of a section of the Kaiparowits Plateau region of Utah was conducted to evaluate the uranium potential of the area.

The following abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the Richfield quadrangle, Utah.

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.

The Delta 1°x2° Quadrangle, Utah contains rocks which range in age from the Precambrian through the Holocene. It lies in the eastern part of the Basin and Range Province, approximately 85 mi southwest of Salt Lake City. Most known uranium resource potential lies in four geographic environments in two geographic areas. Favorable environments are: (1) Tertiary tuffaceous sandstone and conglomerate epigenetic disseminated deposits; (2) volcanic hydroallogenic environments containing uranium-mineralized altered tephra in the beryllium tuff member of the Miocene Spor Mountain Formation; (3) pipes or small diatreme structures in the Paleozoic limestones and quartzites on Spor Mountain, defined as Tertiary volcanogenic hydroallogenic environments; and, (4) alluvial-lacustrine placer environments, on the east and west sides of the Deep Creek Range adjacent to the quartz monzonite Ibapah stock. The significant volume of Miocene rhyolites and tuffs in the Quadrangle contain uncommonly large abundances of uranium and thorium.

From Introduction: "The Price 1ºx2º Quadrangle, in central Utah, (Fig. 1) was studied to identify and evaluate and geologic formations that are favorable for the areas and geologic formations that are favorable for the occurrence of uranium deposits of specific minimum size and grade."

From Introduction: "The Cortez 1º x 2º Quadrangle, southwestern Colorado and southeastern Utah (Fig. 1), was studied to identify and evaluate areas and geologic formations that are favorable for the occurrence of uranium deposits of specific minimum size and grade."

From Introduction: "The Moab 1ºX2º Quadrangle, east-central Utah and west-central Colorado (Fig. 1) was studied to identify and evaluate areas and geologic formations that are favorable for the occurrence of uranium deposits of specific minimum size and grade."

From Purpose and Scope of Study: "The purpose of this study is to provide an evaluation of the favorability of the Vernal, Colorado-Utah, 1º x 2º Quadrangle (Fig. 1) for the occurrence of uranium deposits. The study restricted to indicating geologic units and areas favorable for uranium deposits containing at least 100 tons of U3O8 with an average grade of .01 percent U3O8 or more and less than 1,500m (5,000 ft) deep."

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

The objectives of this North Hill Creek 3-D seismic survey were to: (1) cover as large an area as possible with available budget; (2) obtain high quality data throughout the depth range of the prospective geologic formations of 2,000' to 12,000' to image both gross structures and more subtle structural and stratigraphic elements; (3) overcome the challenges posed by a hard, reflective sandstone that cropped out or was buried just a few feet below the surface under most of the survey area; and (4) run a safe survey.

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.
