Airborne gamma-ray spectrometer and magnetometer survey: Madison quadrangle (WI). Final report

Five uranium anomalies meet the minimum statistical requirements as defined in Volume I. These anomalies are tabulated 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. Anomaly No. 1 is over an area underlain by the Ordovician St. Peter Sandstone (Osp). Anomaly No. 2 is over an area underlain by Ordovician Galena Black River Dolomite (Og). Anomalies No. 3 to No. 5 are over areas underlain by undifferentiated Pleistocene ground moraines
