From introduction: The objective of the investigations is to test the usefulness of these geophysical procedures in connection with exploration for uranium-bearing mineral deposits.

From abstract: The Legin group area comprises five privately owned claims, nine Government claims, and some public land. The area is in parts of secs. 28 and 29, T. 43 N., R. 19 W., New Mexico principal meridian, San Miguel County, Colo. It is about 45 miles from the Government mill at Monticello, Utah, and 50 miles from the Vanadium Corporation of America mill at Naturita, Colo. The Legin group area has yielded a total production of more than 18,000 short tons of carnotite ore that averaged 0.32 percent U30 and 2.5 percent V 205 . Most of this production was accomplished during the years from 1935 to 1944, and from 1949 to October 1951.

The following report covers a reconnaissance for new discoveries of radioactive lignite deposits in the Green River Basin and Uinta Basin of Wyoming and Utah where similar discoveries to previous studies in North Dakota, South Dakota, Montana, and Wyoming were made. Additionally, there were new prospects examined, as well as reconnaissance for uranium deposits.
