On the age of Rhodesian greenstone beltsIsochron ages and initial Sr-87/Sr-86 ratios are derived from Rb-Sr isotopic analyses on metavolcanic rocks from some greenstone belts of the Rhodesian Archean craton. Three mineral isochron ages (about 2.4 billion years) are tentatively suggested to represent the time of an important low-grade metamorphic event.
