Illustrations accompanying a report investigating the locations of vanadium-bearing phosphatic shale in West-Central Wyoming and Southeastern Idaho. The set includes seven maps (Plates I and V-X) showing the location of rock formations in the area and three charts (Plates II-IV) showing the correlation between the occurrence of vanadium deposits and the thin persistent beds of phosphate rock, oolite, siltstone, dolomite, and limestone with which they are interbedded.

Table showing the estimated reserves of vanadium-bearing rock in the Paris-Bloomington, Montpelier, Sublette Ridge, Swift Creek, and Strawberry Creek - Greys River Divide extraction areas in west-central Wyoming and southeastern Idaho. Indicated tonnage and inferred tonnage values are given for each area in millions of tons, along with the percentage of vanadium ore rock, maximum and minimum thickness, and average thickness of the rock in the extraction area.

Discussing Vanadium-bearing phosphatic shale produced in West-central Wyoming and Southeastern Idaho

From abstract: An airborne radioactivity survey of a selected area in the Red Desert, Sweetwater County, Wyoming, containing outcrops of radioactive lignites and shales of known surface extent and uranium content, was flown on flight lines at three levels, respectively 250, 500, and 1,000 feet above the ground and spaced at one-quarter mile intervals. Measurements from three identical dual-channel radiation detectors were simultaneously recorded to obtain data at various distances from natural radioactive sources of known configuration. The radiation intensity measurements were fully corrected for all extraneous effects and were compiled as profiles of radiation intensity, as an isoradioactivity contour map, and as curves showing the relationship between radiation intensity and distance from the source.

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.

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

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."

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 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.

"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)"

Report issued by the Bureau of Mines over an annual study of synthetic liquid fuel production. Results of the annual study are presented and discussed. This report includes maps, tables, illustrations, and photographs.

Report discussing the U.S. Geological Survey's investigation of the stratigraphy of the Phosphoria formation in Wyoming and the phosphate deposits in this area. Analytical data and abstracts of stratigraphic sections of many locations in this area are included.

From abstract: Uranium minerals were discovered in the Pumpkin Buttes area, Campbell and Johnson Counties by the U. S. Geological Survey in October 1951. From June to November 1952, an area of about 750 square miles was examined for uranium deposits, and 211 localities with abnormally high radioactivity were found; uranium minerals are visible at 121 of these localities.

Report discussing the investigation of 750 square miles of land in Wyoming aimed at locating uranium deposits. Information regarding the area, uranium deposits, mineralogy, and results of the exploration are included.
