Report describing chemical analysis of 62 water and 620 sediment samples during a follow-up geochemical survey to search for uranium in the Pueblo quadrangle.

Introduction: Studies of uranium-vanadium occurrences in the Four Corners region show that, with the exception of the Lukachuai area, all of the major deposits in the Morrison formation are grouped around the various igneous masses which are scattered irregularly throughout the Colorado Plateau. The pattern of deposition varies from mountain group to mountain group and each will be described separately. Maps accompany this report to supplement the descriptions of ore occurrences in the vicinity of the La Sal, Abajo, Carrizo, and Henry mountains. Elsewhere, it is believed that a written description will suffice.

"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)

From abstract: Experimental simulation of Colorado Plateau type uranium deposits is divided into seven parts. The first three summarize the essential features of geological occurrence for the ores. The last four parts outline the results of experimental investigation arranged according to each geological group of features influencing mode of occurrence.

From introduction and acknowledgements: This report is written to supplement and complete the record contained in some fifty district and special reports already submitted, and duplication of material in district reports has been studiously avoided. The data herein contained are largely of a regional type, inclusion of which was not wholly appropriate to the district reports.

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.

"The principal uranium deposits in southcentral Wyoming and north-western Colorado are located in or at the margins of broad Tertiary basins. Interesting and possibly commercially significant occurrences are found in other Tertiary and older rocks at widely separated locations within this region. The six maps accompanying this report give the location, name, and ownership of the mines and occurrences from which samples assaying greater than 0.10% U3O8 have been collected. Claim names, location, and ownership are also given for occurrences outside the map areas."
