Description

From Introduction: "The Lander Quadrangle, Wyoming (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Favorable areas are those that are capable of containing uranium deposit of at least 100 tons of U3O8 in rocks with a minimum average ore grade of 0.01%."

Notes

Abstract: The Lander Quadrangle, Wyoming, was evaluated to a depth of 1500 m to identify environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. The evaluation used criteria established for the National Uranium Resources Evaluation program. The methods of surface investigations included evaluation of aerial radiometric and hydrogeochemical stream-sediment reconnaissance data, verification of some reported uranium occurrences, and general field geology with rock, water, and sediment sampling. The subsurface evaluation was accomplished through the use of 230 various oil-well logs. The results of this investigation identified three environments favorable for sandstone uranium deposits in Eocene fluvial sediments. These environments are within the Battle Spring and upper fort Union Formations of the northern Great Divide Basin and within the Wind River and the Wagon Bed Formations of the southwest Wind River Basin. Eight other formations were examined and were found unfavorable for uranium environments. The Precambrian rocks in the wind River Mountains appear to be somewhat depleted in uranium. The Lewis Shale, Lance Formation, and portions of the Precambrian units were not evaluated due to time and access constraints. More field work is needed to determine the sources of most of the reported uranium anomalies and the validity of those that were not field checked.
