Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California
From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.
