Description:
Report issued by the Bureau of Mines over the oil and gas fields of Wyoming. As stated in the summary, "this study contains individual reports on 271 oil and gas fields in Wyoming. The location of each field is given; and, where available, maps of the fields, surface formations, and elevations" (p. 1).
Description:
A paper about Split Rock formation of Miocene age in central Wyoming. It contains mostly consolidated quartz sandstone with lesser amounts of tuff, pumicite, limestone, and claystone.
Description:
A report which presents the geologic results of an exploration program in the Lost Creek area by the U.S. Geological Survey in 1951-52 on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Description:
A report about 100 square miles of metamorphosed Precambrian sedimentary and volcanic rocks in Wyoming. The district in which they are located is known for its gold, but iron deposits of high economic potential are being developed in the northwest part.
Description:
A report about two new geologic formations in Wyoming. The Foote Creek Formation consists of beds of fine-grained sandstone with shale, siltstone, and coal beds. The Dutton Creek Formation consists of beds of coarse-grained locally conglomeratic sandstone.

Description:
A report about the Powder River Basin in northeastern Wyoming which is a physiographic unit bounded on the west by the Bighorn Mountains. There are sedimentary rocks which range in age from Cambrian to Oligocene.
Description:
A report about the geology of the the Crazy Woman Creek area in Wyoming. Rocks of every system except the Silurian and Devonian are present in the area.
Description:
A report which examines the sedimentary rocks deposited along a segment of the west coast of the interior seaway of North America in southwest Wyoming during the late Santonian and early Campanian subages of the Late Cretaceous Epoch.
Description:
A report about 24 townships in Wyoming which were geographically mapped. Fourteen of them contain uranium-bearing coal. There are 30 coal beds in these locations and seven of them contain the uranium-bearing coal.
Description:
From introduction: The compilation of the tectonic map of Wyoming east of the overthrust belt (area 6, fig. 2) was done by the U. S. Geological Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. Structures shown on the map have been obtained from published geologic maps and from unpublished data supplied by Government agencies, private companies, and independent geologists. The tectonic map of Wyoming east of the overthrust belt is only a progress report; a…

Description:
From introduction: During three months of the summer of 1952, a geologic and radiometric reconnaissance examination for uraniferous materials in the peripheral parts of the Powder River structural basin in northeastern Wyoming (fig. 1) was made by the Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. The purpose was to find, describe, locate, and sample deposits of uraniferous or radioactive materials other than those in the central part of the Powder Rive…

Description:
Abstract: A reconnaissance was made of a large part of the Powder River Basin, Wyoming, during the summer of 1952 to search for uranium deposits in parts of the basin other than the Pumpkin Buttes area. No uranium deposits of economic interest were found, but some rocks of the Tertiary Fort Union formation and the Cretaceous Inyan Kara group were found to be sufficiently uraniferous to justify further search in rocks of these units. Analyses of samples of sandstones, baked shales, and siltstone…

Description:
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 Pl…

Description:
GEOTHERM sample file contains 356 records for Wyoming. Three computer-generated indexes are found in appendices A, B, and C of this report. The indexes give one line summaries of each GEOTHERM record describing the chemistry of geothermal springs and wells in the sample file for Wyoming. Each index is sorted by different variables to assist the user in locating geothermal records describing specific sites. Appendix A is sorted by the county name and the name of the source. Also given are latitu…

Description:
Surface remedial action is complete at the Spook Uranium Mill Tailings Remedial Action Project site in Wyoming. Based on an evaluation of site characterization data, the US Nuclear Regulatory Commission, US Department of Energy, and state of Wyoming have concurred in the determination that a program to monitor ground water is not required because ground water in the uppermost aquifer is Class 3 (limited use) (40 CFR 192.21(g)(1993)).
Description:
More than nine-tenths of the Upper Cretaceous rocks in northeastern Wyoming are fine-grained shales, mudstones, and
calcareous marls. A comparative study of the mineralogy, chemical and mechanical composition, density and porosity,
fissility, and lamination of samples of these rocks discloses several relations that throw light on the geologic history and
structural deformation of the region, and perhaps on its oil and gas possibilities.
