Geologic guides to carnotite deposits on the Colorado Plateau
The carnotite deposits of the Colorado Plateau have been our principal domestic source of uranium and vanadium. Several of the geologic features associated with the deposits have been of considerable value in prospecting and they are now being used successfully by the U.S. Geological survey in its program of exploration drilling on the Colorado Plateau. The deposits occur in lenticular sandstone beds1 mostly in the Morrison formation. Sandstone less than about 40 feet thick rarely contains sizeable ore deposits. Sandstone that is pale to light brown, and speckled with stain, is most favorable; ...
