From introduction: This volume contains information and survey results pertaining specifically to the Shelby NTMS 1:250,000 scale Quadrangle, Montana, one of a group of 12 such quadrangles in Arizona, Idaho, Montana, New Mexico, South Dakota, and Washington included in an aerial radiometric and magnetic reconnaissance survey. General information concerning the instrumentation and methods used in data acquisition, processing, and interpretation is presented in Volume 1 of this final report.

Appendix containing tables to accompany a report on aerial radiometric and magnetic reconnaissance survey of the Shelby Quadrangle.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Great Falls quadrangle including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

This report provides the results to an airborne radiometric reconnaissance made in central Montana, the Sweetgrass Hills and Arch area, and Clancy area of the Boulder batholith that was completed in October 1953. This report is divided into three parts, each area is discussed separately according to its geology, the airborne procedures employed, and the conclusions reached.

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."

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.
