Abstract
Abstract This note reports on the Rb, Sr and K chemistry and Sr isotope composition of sheared gneisses from the Limpopo mobile belt, an Archean high-grade terrain in southern Africa. Retrogression during shearing appears to have shifted the chemical and isotopic composition of the gneisses away from those of the surrounding unsheared granulites towards compositions characteristic of certain late Archean granites within the mobile belt and on the adjacent Zimbabwe craton. These results bear on the issues of RbSr dating of high-strain events and of granite genesis in the Limpopo belt.
