Bundelkhand and Dharwar Cratons (Indian Shield): Comparison of Crustal Evolution in Archean Time

Vinod K Singh

Open full text 4 citations

Abstract

Comparison of the Meso-Neoarchean crustal evolution of the Bundelkhand, Western and Eastern Dharwar cratons shows that geodynamic mechanisms, similar to modern plate-tectonic and mantle-plume mechanisms, were active in that period. Each of the cratons displays its own crust formation pattern. It seems that in Archean time the Bundelkhand craton and the Western and Eastern Dharwar cratons were the various parts of the Kenorland Supercontinent, rather than one block.
