Aerial gamma ray and magnetic survey, Cincinnati quadrangle, Indiana, Ohio, and Kentucky. Final report

The Cincinnati quadrangle of Indiana, Ohio, and Kentucky covers 7100 square miles of largely agricultural land in the easternmost Midwestern Physiographic Province. Thin Paleozoic strata overlie Precambrian basement in this area. The Paleozoic units are largely masked by Quaternary glacial deposits that thicken to the northwest and northeast. No uranium deposits are known within the quadrangle. The interpretation process defined 86 anomalies, all of which appeared to be culturally induced. None contain significant measured quantities of uranium. Magnetic data appear to be largely in agreement with present structural interpretations, though some other small structures are suggested that could represent complexities in the Precambrian basement
