From abstract: Between mid-May and late June 1976, 3409 water and water-transported sediment samples were collected from 1781 locations spread over an approximate 17 000 kilometer area of northwestern Montana. All of the samples were analyzed for total uranium at the LASL, using standardized procedures and rigorous quality controls--the waters by fluorometry and the sediment (and those waters with >10 parts per billion uranium) by delayed-neutron counting methods.

This document consists of maps evaluating selected parts in Pennsylvania and rocks in Oklahoma.

Introduction: The areas of study include parts of the Wichita uplift, Arbuckle uplift, Hunton-Pauls Valley uplift, Central Oklahoma platform, Muenster-Waurika arch, and Anadarko basin (Fig. 1.1-1). Rocks examined include the Precambrian granite of the Arbuckle uplift, Cambrian igneous rocks of the Wichita uplift, and Pennsylvanian-Permian sedimentary rocks derived in large part from those two uplifts and, to a lesser extent, from the Ouachita system.

From addendum: Two types of analyses for uranium in the stream-sediment samples are presented. One split of the stream-sediment samples was sent to Resource Associates of Alaska's laboratory, where they were analyzed for U by the fluormetric method after acid extraction. This is the method employed for U by most laboratories. The completeness of uranium extraction unavoidably varies with the particular type of uranium-bearing minerals present and possibly with the amount of iron, manganese, and carbonaceous material present, which can interfere with the extraction. Analyses by the method are shown in the text and appendix columns with the designation "RAA."

This report contains aerial gamma-ray and magnetic quadrangle maps of portions of northeastern Oklahoma.

Appendix containing single-record data listings to accompany a report on aerial radiometric and magnetic survey of the Torrington and Casper quadrangles in Wyoming and Nebraska.

Purpose: This study was conducted in order to assess the character and extent of Tertiary volcanic rocks and volcanic-derived sedimentary rocks as potential uranium host and (or) source rocks.

From abstract: Several low-level radiometric anomalies had been detected in an airborne survey of the Copper River Basin. This report presents the results of field and laboratory research on the origin of the anomalies, and the low radiometric background of the Copper River Basin.

Supplementary data containing radiometric readings of several locations to accompany a report on low-level airborne radiometric anomalies in the Copper River Basin Region, Alaska.

Rock and stream-sediment samples were collected to define areas favorable for uranium deposits northeast of Gunnison, Colorado. Areas considered most favorable for further exploration are: (1) the Bronco Mountain area, approximately 10 mi south of Taylor Park Reservoir, (2) the area near the Big Red mine, and (3) the area 5 mi north-northeast of Taylor Park Reservoir. On the basis of known deposits in the Marshall Pass and Cochetopa districts, fault contacts between Precambrian granites and Paleozoic or Mesozoic sedimentary rocks are favorable structural sites.

From objectives: This report describes the physical geology of the Catahoula Formation-its genetic stratigraphy, structure, mineralogical composition, and post-depositional history and discusses the known distribution of uranium within the context of these geological parameters. Emphasis is on definition of primary physical and historical factors affecting the mobilization, transport, and concentration of uranium in the Catahoula Formation.
