MetadataShow full item record
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. This report provides quantitative expressions of the value of these geologic features as guides to ore have been established as a result of recent studies by the Geological survey based on geologic logs of more than 2,500 drill holes.
