Aerial gamma ray and magnetic survey: Fairmont quadrangle, Minnesota and Iowa. Final report

DOI:https://doi.org/10.2172/6893022· OSTI ID:6893022
The Fairmont quadrangle covers 6900 square miles of the northern Midwestern Physiographic Province in northern Iowa and southern Minnesota. The surface is covered with Quaternary glacial and related deposits. The subglacial surface contains Precambrian basement, and some thin Phanerozoic units. A search of available source material revealed no known uranium deposits. A total of 91 anomalies were detected and briefly discussed in this report. None were considered significant, and all appear to represent cultural features. Quadrangle-wide average concentrations of K, U, and T are all extremely low. Magnetic data appear to illustrate complexities in the underlying Precambrian.
