Abstract

We have compiled 11 reliable paleomagnetic poles from Peninsular India in order to test a variety of paleogeographic scenarios. Precambrian peninsular India represents an amalgam of five cratonic nuclei known as the Dharwar, Bastar, Singhbhum, Bundelkhand cratons, and the Aravalli-Banded Gneiss Complex (BGC). The Bundelkhand craton and Aravalli-BGC (North Indian Blocks) are separated from the other three regions (South Indian Blocks) by an WSW-ENE transcontinental belt known as the Central Indian Tectonic Zone (CITZ). Paleomagnetic and geochronological data from these regions indicate that the South Indian blocks were assembled by at least 1.765Ga. Peninsular India was amalgamated along the CITZ between 1.1 and 0.9Ga.
