Abstract
Four methods of dating Colorado Plateau carnotite have been examined and evaluated: mineralogic methods, radioactive-equilibrium methods, lead-uranium-ratio methods, and lead-isotope methods. The data on 12 high-grade samples, from a suite of 50 representative carnotite ores, are presented.
