Preliminary geologic map of the Verdure 4 SW quadrangle, San Juan County, Utah

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.

The following report covers investigations on the geology of the Kern River uranium area in Kern County, California, as well as the small uranium ore deposits erratically distributed along fractures.

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.

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.

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.

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 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.

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.

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.

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.
