The Danville quadrangle covers approximately 7250 square miles of area in Illinois and Indiana within the Midwestern Physiographic Province. Thick glacial deposits overlie lower Paleozoic strata in this area. Precambrian crystalline material revealed no known uranium deposits. A total of sixty-seven uranium anomalies were detected and are discussed briefly in this report. None were considered significant and all appear to be related to cultural features. Magnetic data appears to be in agreement with existing structural interpretations of the area, though some high gradient areas may represent complexities in the Precambrian basement material.
