Some Uranium Occurrences in West Texas

From the Abstract: Uranium minerals have been found at several localities in west Texas. In the King Mountain area in southwestern Upton County carnotite forms coatings along joint planes and in borings in marineCretaceous limestone. In the Hueco Mountains area in El Paso and Hudspeth counties carnotite and similar secondary uranium minerals form coatings in caliche and colluvium of Pleistocene ( ? ) or Recent age, and along joints and bedding planes in limestone of Permian age. No uranium ore has been produced, however, from either area.
