Description: From abstract: The uranium deposits of the Mayoworth area, Johnson County. Wyo., are in oolitic limestone at the base of the Sundance formation of Late Jurassic age. The uranium mineral has been identified as metatyuyamunite, a hydrous calcium uranium vanadate, that coats joints and fractures and replaces calcite in both the cement and the oolites. The known deposits of the area are of sub-ore grade, have a high lime content, and are not of economic importance at this time.
