Geophysical logs for 28 holes drilled in the Quartz-Pebble Conglomerates in Southeast Wyoming by the Bendix Field Engineering Corporation, Grand Junction, Colorado.

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 latitude, longitude (both use decimal minutes), township, range, section, GEOTHERM record identifier, and temperature (/sup 0/C). Appendix B is sorted by county, township, range, and section. Also given are name of source, GEOTHERM record identifier, and temperature (/sup 0/C). Appendix C is first sorted into one-degree blocks by latitude, and longitude, and then by name of source. Adjacent one-degree blocks which are published as a 1:250,000 map are combined under the appropriate map name. Also given are GEOTHERM record identifier, and temperature (/sup 0/C). A bibliography is given in Appendix D.

From Introduction Purpose and Scope: "The Arminto 1º x 2º quadrangle, in central Wyoming (Fig. 1), was evaluated to identify geologic environments that exhibit characteristics favorable for uranium deposition. Evaluation, consisting of three separate and distinct phases, started in October 1978 and ended in March 1980. It must be emphasized that this report is meant to be a preliminary reconnaissance-type study to identify favorable environments, as defined above."

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 siltstones taken during the reconnaissance show these rocks are considerably more vanadiferous than the average sandstone, or clay and shale.

The following report is the first in a series of volumes presenting data recorded during the months of August and September, 1978, from a radiometric and magnetic survey taken in four quadrangles between Wyoming and southern Montana (Forsyth, Hardin, Sheridan, Arminto, Newcastle and Gillette)

From abstract: The uranium deposits of the Mayoworth area, Johnson County. Wyo., are in oolitic limestone at the base of the Sundance formation of Late Jurassic age. The uranium mineral has been identified as metatyuyamunite, a hydrous calcium uranium vanadate, that coats joints and fractures and replaces calcite in both the cement and the oolites. The known deposits of the area are of sub-ore grade, have a high lime content, and are not of economic importance at this time.
