H. D. Zeller 1955 A reconnaissance investigation for uranium-bearing carbonaceous materials was made in three major areas of southern Utah: Kaiparowits Plateau, Henry Mountains, and Kolob Terrace. No uranium deposits of economic interest were found. A few l- to 2-foot beds of carbonaceous shale in the Dakota(?) sandstone contain 0.006-0.007 percent uranium. Other carbonaceous sediments that were examined contain 0. 002 percent or less uranium. application/pdf 10.3133/cir349 en U.S. Geological Survey, Reconnaissance for uranium-bearing carbonaceous materials in southern Utah reports
