PB AND SR ISOTOPIC DISEQUILIBRIUM BETWEEN ORTHOPYROXENE AND PLAGIOCLASE IN THE CRITICAL ZONE, BUSHVELD, S. AFRICAThis method demonstrates that some of the important rock-forming minerals in the Bushveld appear to be in isotopic disequilibrium. This would suggest that whole-rock isotopic analysis could...
