Appendices containing supplementary analytical data of various stream, sediment, and rock samples, in addition to uranium occurrence reports and elemental concentration data to accompany a report on U.S. uranium resources in the Dubois Quadrangle, Idaho and Montana.

From Purpose and Scope: "The Dubois Quadrangle, Idaho and Montana (Fig. 1), was studied to identify geologic environments and delineate areas favorable for uranium deposits. These reports summarized field observations and contained preliminary evaluations of geologic environments for uranium deposition. The identification of environments favorable for uranium deposition involved collection and interpretation of radiometric, geochemical, and geologic data."

From abstract: All geologic conditions in the Dillon Quadrangle (Montana and Idaho) have been thoroughly examined, and, using National Uranium Resource Evaluation criteria, environments are favorable for uranium deposits along fractured zones of Precambrian Y metasediments, in the McGowan Creek Formation, and in some Tertiary sedimentary basins.

"Field and laboratory data are presented for 1005 water samples from the Wallace Quadrangle, Idaho; Montana. The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee."

Recorded data taken from field samples of filtered spring, stream, and well water, and acidified stream and lake water from the Wallace quadrangle in Idaho and Montana.

Recorded laboratory analysis for samples of filtered spring, stream, and well water, and acidified stream and lake water from the Wallace quadrangle in Idaho and Montana.

Final report of the airborne gamma ray and total magnetic field survey for the Wallace quadrangle, Montana-Idaho. Sections I through IV of this report present information and results associated with this specific survey. Section V gives the data acquisition and the processing procedures.

Appendices containing supplementary analytical data of stream-water and stream-sediment samples, in addition to geochemical analyses of rock samples for the Dillon and Dubois Quadrangles. Also included are detailed uranium-occurrence reports for twelve deposits in the Dillon quadrangle, which include including a description, uranium analysis, exact location, deposit type, and features of the host rock.
