Determination of the age of rocks by whole rock Sm-Nd isochron method has several limitations imposed by petrogenetic processes. If the age of the rocks can be determined by other independent methods, the Sm-Nd system provides a wealth of information to understand crustal genesis. Sm-Nd isotopic studies of metabasaltic rocks of the Archaean Kolar and Ramagiri Schist belts in the eastern Dharwar Craton indicate that the system was disturbed by postmagmatic fluid alteration processes associated with terrane accretion.
