Abstract
WE present here the results of a Rb–Sr age and isotope study of granite (about 70% SiO2) from the north-eastern sector of the Mont d'Or formation in the central part of the Rhodesian Archaean craton (Fig. 1). A nine-point Rb–Sr whole rock isochron (Fig. 2, Table 1) yields an age of 3,420±60 Myr, with an initial 87Sr/86Sr ratio of 0.711±0.001 (both errors at 1 σ). We regard this as the age of intrusion.
