Summary

The post-Dharwar basic dikes from Chitaldrug and Shimoga schist belts have been analysed to determine their major, minor and trace-element composition. The comparison of the results from these formations (1.4–0.95 b.y.) with those of the early Precambrian metabasalts (2.4 b.y.), which are indicative of a thin crust at the time of their extrusion shows significant differences between them. Utilizing this and results of similar studies on corresponding formations it is suggested that the present thickness of this part of the crust might have been obtained after the extrusion of the early Precambrian basalts and before the intrusion of the middle Precambrian dolerites.
