OSTI ID:6311979

Twenty-three uranium anomalies meet the minimum statistical requirements as defined in Volume I. These anomalies are listed and are shown on the Uranium Anomaly Interpretation Map. Potassium (%K), equivalent Uranium (ppM eU), equivalent Thorium (ppM eTh), eU/eTh, eU/K, eTh/K, and magnetic pseudo-contour maps are presented in Appendix E. Stacked Profiles showing geologic strip maps along each flight-line, together with sensor data, and ancillary data are presented in Appendix F. All maps and profiles were prepared on a scale of 1:250,000, but have been reduced to 1:500,000 for presentation in Volume II. Anomalies No. 1 and No. 2, and No. 19 are over areas underlain by the Radnor Till member (Qti) of the Pleistocene Glasford formation. Anomalies No. 3 and No. 5 are over areas underlain by Pleistocene moraine and other deposits of the Fairgrange Till member (Qwf, Qwfm) of the Wedron formation. Anomaly No. 4 is over an area underlain by the Pleistocene Batestown Till member (Qwb) of the Wedron formation. Anomalies No. 6 and No. 7 are over areas underlain by the Delavan Till member (Qwd) of the Pleistocene Wedron formation. Anomalies No. 8 and No. 20 are over areas underlain by Pleistocene moraine deposits of the Yorkville Till member (Qwym) of the Wedron formation. Anomalies No. 9, No. 12, and No. 14 are over areas underlain by Pleistocene moraine deposits of the Snider Till member (Qwsm) of the Wedron formation. Anomalies No. 10, and No. 15 to No. 16 are over areas underlain by the Snider Till member (Qws) of the Wedron formation of Pleistocene age. Anomaly No. 11 is over an area underlain by the Pleistocene Snider Till member (Qws) of the Wedron formation and Cahokia Alluvium (Qc).
