Aerial radiometric and magnetic reconnaissance survey of the Eagle-Dillingham area, Alaska Mt. McKinley Quadrangle

The results of a high-sensitivity aerial gamma-ray spectrometer and magnetometer survey of the Mt. McKinley Quadrangle, Alaska, are presented. Instrumentation and methods are described in Volume 1 of this final report. Statistical and geological analysis of the radiometric data revealed six uranium anomalies worthy of field checking as possible prospects. Two are located over granites which are believed to have the best potential for future economic vein-type uranium deposits. Three anomalies may be caused by sedimentary uranium in the Tanana-Kuskokwim Lowland, and one anomaly, located in Paleozic sedimentary rocks, may be associated with slates
