Airborne gamma-ray spectrometer amd magnetometer survey: San Francisco quadrangle (California). Final report
Ten 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, together with the interpretation of the magnetic data. Potassium (%K), equivalent Uranium (ppM eU), equivalent Thorium (ppM eT), eU/eT, eU/K, eT/K, and Magnetic Pseudo Contour Maps are presented in Appendix E. Stacked Profiles showing geologic strips 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 1:150,000, but have been reduced to 1:500,000 for presentation in Volume II. A number of short-wavelength magnetic anomalies are associated with ultrabasic intrusives. These intrusives crop out along the major northwest-trending fault zones that traverse the map area, and thus form a magnetic expression of the faults. Part of a long-wavelength anomaly that extends off the map area is present in the northeast corner of the quadrangle. The source of this anomaly is interpreted as a large, deep-seated magnetic body - possibly gabbro.
