Abstract: This report consists of four parts, the first three being descriptions of investigations compiled in the period October 1st, 1953 to April 1st, 1954; the fourth part is a summary of progress of the research based on our entire investigations completed prior to April 1st, 1954. The first part comprises a set of preliminary experiments investigating the mineral composition of the sandstones in thin sections, in an attempt to differentiate barren from ore-bearing sandstones. It appears that there are more rock-fragments and particularly more volcanic rock fragments in the ore zone (zone 4, Well C, Bull Canyon). In addition, silica cement appears to be associated with ore and carbonate cement with barren sediments. The second part details the investigation of the mudstones of the Bull Canyon Wells . A mixed layer lattice "illite" and a kaolin mineral are the most prominent in "normal" mudstones. Dye tests suggest there are differences between the clay minerals in the sandstone matrix of the ore zone and barren zone. In addition, the mudstone zones appear to differ in the response to the dye tests. The third part of the report details the bulk density determinations for cores from well B. The results confirm …

Introduction: Studies of uranium-vanadium occurrences in the Four Corners region show that, with the exception of the Lukachuai area, all of the major deposits in the Morrison formation are grouped around the various igneous masses which are scattered irregularly throughout the Colorado Plateau. The pattern of deposition varies from mountain group to mountain group and each will be described separately. Maps accompany this report to supplement the descriptions of ore occurrences in the vicinity of the La Sal, Abajo, Carrizo, and Henry mountains. Elsewhere, it is believed that a written description will suffice.

Abstract: The southwestern part of the Colorado Plateau province was studied to test results from experimental simulation of Colorado Plateau type uranium deposits and to search out additional agents influencing uranium precipitation which might be investigated experimentally.

Abstract: Weak uranium mineralization is widespread throughout the Uinta Basin of northeastern Utah and northwestern Colorado, in rocks ranging in age from Permian to Eocene. No commercial ore bodies are known, although formations there have characteristics elsewhere considered favorable for ore deposition.

Abstract: An airborne radiometric survey of the Dakota sandstone and Morrison formation in the Canon City embayment was conducted by the Atomic Energy Commission from November 1, 1953 to December 5, 1953.

From abstract: Experimental simulation of Colorado Plateau type uranium deposits is divided into seven parts. The first three summarize the essential features of geological occurrence for the ores. The last four parts outline the results of experimental investigation arranged according to each geological group of features influencing mode of occurrence.

Several relatively small copper-uranium deposits have been found in southwestern Utah along the contact of the Shinarump and Moenkopi formations of Triassic age, at least from the San Rafael Swell area of Emery County, southward through central and eastern Garfield County, southwestward into western Kane County, and westward into the southern part of Washington County.

The following report studies uranium ore deposits discovered in the Browns Park Formation, south-central Wyoming and northwest Colorado.

"The principal uranium deposits in southcentral Wyoming and north-western Colorado are located in or at the margins of broad Tertiary basins. Interesting and possibly commercially significant occurrences are found in other Tertiary and older rocks at widely separated locations within this region. The six maps accompanying this report give the location, name, and ownership of the mines and occurrences from which samples assaying greater than 0.10% U3O8 have been collected. Claim names, location, and ownership are also given for occurrences outside the map areas."
