From introduction: Geologic mapping was done in the Pumpkin Buttes area, Johnson and Campbell Counties, Wyoming, during the summer of 1952 on behalf of the Atomic Energy Commission. The objectives of the work were: to find uranium deposits, to study their distribution, habit, and occurrence, and to use such knowledge as guides in outlining areas favorable for mineralization.

From abstract: A sequence of slightly radioactive Pliocene(?) rocks in the Split Rock area of central Wyoming is at least 600 feet thick, underlies an area of more than 25 square miles, and consists of alternating beds of tuffaceous shale, sandstone, and pumicite. Only a small part of the section has been examined. In addition to the uranium content of the strata, there has been secondary concentration of uranium in brecciated limestone similar to spring deposits that could be of Pliocene or Pleistocene age.

Abstract: An airborne radiometric survey of parts of the east flank of the Big Horn Mountains was begun on June 23, and completed on August 27, 1952. An area of approximately 250 square miles was covered, and only two anomalies were found in the entire area. Flight lines were arranged in accordance with the geology of the area, particular attention being given to formations the stratigraphic equivalents of which are known to be uranium bearing in other areas. Two additional zones of radioactivity were found by ground investigation, but assays from both the ground and the airborne discoveries showed no economic uranium deposits.

Summary: The Lost Creek schroeckingerite deposit in Sweetwater County, Wyo., has attracted attention in the past both as an occurrence of comparatively rare minerals and more recently as a possible source of uranium ore. During the summer of 1948 a newly-formed company by the name of Uranium, Inc., explored part of the deposit by bulldozer trenching and drilling. under the technical direction of the Minerals Engineering Company of Grand Junction, Colo. Examination of the significant exposures of the schroeckingerite deposit indicated that the uraniferous beds are discontinuous and that their areal distribution is erratic. The overburden has an average thickness of 2.5 feet.

From introduction: This report details the reconnaissance for uraniferous lignites in North Dakota, South Dakota, Montana, and Wyoming during 1948 and 1949.

From abstract: A reconnaissance search for uraniferous rocks in the northeastern part of the Wind River Basin was made in July and August 1951 in the course of other work. In addition to Tertiary tuffs and associated lignite, coal, and carbonaceous rocks, some radioactivity anomalies, chiefly in granite, which had been detected by airborne equipment in November 1950, were checked on the ground. A tuff of middle or late Eocene age containing 0.003 percent uranium was as high in uranium as any rock found.

The following report covers a reconnaissance for new discoveries of radioactive lignite deposits in the Green River Basin and Uinta Basin of Wyoming and Utah where similar discoveries to previous studies in North Dakota, South Dakota, Montana, and Wyoming were made. Additionally, there were new prospects examined, as well as reconnaissance for uranium deposits.

Report discussing a geological study performed to find uraniferous lignites in North Dakota, Eastern Montana, north-central Wyoming, and northwestern South Dakota. "Deposits of uraniferous lignites were discovered at Blue Buttes, eastern Montana; and at North Cave Hills, South Cave Hills, and at Slim Buttes in northwestern South Dakota."

Report discussing the reconnaissance for radioactive uraniferous rocks in parts of Colorado, Wyoming, and Utah. Regional geology of each area, results of regional reconnaissance, and miscellaneous prospects are included.

Abstract: During parts of July, August, and September 1951, a reconnaissance was conducted in parts of Colorado, Wyoming, Utah, and Idaho in search of new deposits of uranium-bearing carbonaceous rocks. One significant uranium occurrence was found, the Fall Creek deposit, Bonneville County, Idaho. Several additional localities were discovered that contain uranium in concentrations many times that normally found in carbonaceous rocks.

Report discussing an investigation of copper deposits in sandstone that were believed to be possibly uraniferous, and uraniferous asphaltite deposits.

Report describing the phosphorite deposits of the western United States with the objective of outlining features that are common to both the Kara Tau phosphorite deposits of Russia and the western United States deposits in an effort to define their origin.

"his interim report presents the grade and tonnage data collected during exploration at the Lost Creek schroeckingerite deposit, Sweetwater County, Wyoming, Between July 1951 and February 1952. Discussions of he geologic results of exploration (lithology, mineralogy, structure, origin, etc.) are not included in this report and consequently the detailed lithology and structure have been omitted from the illustrations (figs. 1-7)"

From Introduction: "A preliminary report of the work was published in April 1947, and this bulletin supplements Report of Investigations 4104 and describes the results of the entire investigation."
