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.

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.

Abstract: Uranium occurs in the North Park(?) formation of Pliocene(?) age in the Miller Hill area, about 25 miles south of Rawlins, Carbon County, Wyo. As much as 0. 5 percent uranium is contained in grab samples, but only about 1000 tons of rock are known to contain as much as 0. 03 percent uranium. Beds of brecciated, silicified limestone 3 to 10 feet thick contain the principal concentrations of uranium. Lesser concentrations are found in calcareous sandstone and quartzite. Uranophane, Ca(UOz)2SizO 7 . 6HZO, the principal uranium'mineral, has been deposited in vugs, as fracture and surface coatings, and as a disseminated constituent of the rock. Uranium also occurs in quantities too small to be megascopically visible in dark-colored chalcedony, lime stone, sandstone, and quartzite beds.

The following report covers studies and investigations of uranium deposits in the Black Hills of South Dakota and Wyoming. The ore minerals include carnotite, tyuyamunite, metatyuyamunite, corvusite, rauvite, uraninite, and coffinite, as well as minor amounts of other uranium and vanadium minerals.

Report discussing an investigation of the geology of the Miller Hill area in Wyoming. This area's rocks were shown to contain varying amounts of uranium.

Report presenting the results of core drilling in Sweetwater county, Wyoming aimed at finding uraniferous coal. Information regarding the locations that were drilled, progress made in drilling, geology of the area, reserves of uraniferous coal, and future plans are included.

Abstract: A study was conducted for the resolution of sediment source areas in the Big Sandy River basin, southwestern Wyoming. Suspended-sediment and bedload data were collected in order to determine total sediment transport at several locations within the basin. The bedload data were compared to the Einstein bedload function and total load data were compared to the Colby method. The bedload comparison showed a higher estimation of transport rates with Helley-Smith sampler measurements than with the Einstein beadload function. The Colby method yielded higher transport rates at high flows and lower transport rates at low flows than the measured total transport rate. The Big Sandy reservoir acts as a control in the basin. The area upstream of the reservoir was interpreted separately from the area downstream for source-area determination. In the arid plains upstream of the reservoir, the amount of sediment transported increased 98 percent with an increase in runoff of only 1 percent.

From introduction: One purpose of this study was to describe streamflows of the Green River and its tributaries. In addition to describing the cause and occurrence of streamflows in the study area, a brief discussion of how streamflow data are collected and summarized is presented as background information to users of this report who may be unfamiliar with streamflow measurement. The second and primary purpose of this study was to describe hydraulic characteristics of streams in the study area.
