National Uranium Resource Evaluation: Geophysical Interpretation of Airborne Magnetic Data, Midnite-Sherwood Mines, NE Washington

摘要

The study area is primarily confined to the northeast portion of the Ritzville Quadrangle in northeastern Washington, although very small portions of the Sandpoint and Spokane Quadrangles are included in the aeromagnetic interpretation. This region is most noted for the Midnite uranium mine, the largest known deposit of its type located in North America. Following the description of the quadrangles in the introduction, this report contains the following information: general geology; general structure; magnetic lineations; detailed structure with eight (1:24,000) interpretation maps and six (1:62,500) composite interpretation maps; bibliography; Appendix I - description of microanalysis; Appendix II - magnetic maps 1:62,500 scale; Appendix III - structural interpretation overlays.
