Aerial gamma-ray and magnetic survey: Toledo quadrangle, Ohio and Michigan. Final report

Technical Report · Mon Jun 01 04:00:00 EDT 1981

OSTI ID:6042106

The Toledo quadrangle of Ohio, Michigan, and Ontario, Canada covers 7,100 square miles of the Midwestern Physiographic Province. Moderate to thick Paleozoic strata overlie Precambrian basement, with Quaternary glacial sediments covering the entire quadrangle surface. A search of available literature revealed no known uranium deposits. Thirty uranium anomalies were detected and are discussed briefly. Radiometric data appears to reflect differences in material between morainal and lacustrine deposits. None of the anomalies were considered significant and all appear to be related to cultural features. Magnetic data appears to be in agreement with existing structural interpretation of the area, with the exception of one isolated feature. This feature may be attributed to lithologic and/or structural complexities in the Precambrian basement.
