Geology and Uranium Evaluation of the Precambrian Quartz-Pebble Conglomerates of the Needle Mountains, Southwest Colorado: Final Report
From purpose of study: The Vallecito Conglomerate of the Needle Mountains area in southwestern Colorado was studied to evaluate the uranium potential of the unit and to test the applicability of the uraniferous Precambrian pebble-conglomerate exploration model in this area. The main thrust of this project is the Vallecito Conglomerate, but the Uncompahgre Formation, which is also in the Needle Mountains area has basal conglomerate that was investigated in a reconnaissance mode. Five specific objectives have been formulated to meet the overall purpose of this project, and these include: a) Determine the uranium distribution in the Vallecito Conglomerate and the basal conglomerate of the Uncompahgre Formation. b) Evaluate the uranium resources of the area to the degree possible utilizing available information and personal field investigations. c) Test the validity of application of the Precambrian quartz-pebble conglomerate model to this area. d) Recommend detailed studies and delineate drilling sites in the area to further evaluate the uranium resources if warranted. e) Recommend additional geologic, geophysical and geochemical studies which would bear directly on evaluation of uranium resources of the Precambrian pebble conglomerates in the Needle Mountains area.

Evaluation of Possible Radioactivity Transport in Groundwater
"The possibility of radioactivity transport in the groundwater system as the result of a hypothetical maximum credible gas leak was evaluated." "The present study confirms the low radiation levels in the groundwater predicted in the initial calculations." (from Summary)

Research and development of geophysical and geochemical techniques for uranium exploration on the Colorado Plateau
The general purpose of the work performed under this contract was to develop geophysical and geochemical methods and techniques which would be effective aides in exploring for uranium and to appraise their effectiveness as determined by the results of field surveys in prospective areas about to be drilled, or in an area where ore is already known.
