Bundelkhand, Aravalli and Dharwar cratons Indian Shield: comparison of Archean crustal evolution and location in the Kenorland Supercontinent structure
Keywords: Archean; crustal evolution; geodynamics; Indian Shield; Bundelkhand Craton; Western Dharwar Craton; Eastern Dharwar Craton; Aravalli Craton
Comparison of the Meso-Neoarchean crustal evolution of the Bundelkhand, Aravalli, Western and Eastern Dharwar Cratons shows that geodynamic mechanisms, similar to modern plate-tectonic and mantle-plume mechanisms, were active in that period. The Mesoarchean crustal evolution of the Bundelkhand Craton is considerably different from that of other cratons discussed here in that it comprises subduction-accretion processes, while in other cratons plume processes were more active in this period. In the Neoarchean (2.7-2.5 Ga), all the cratons display subduction-accretion processes. Each of the cratons displays its own crust formation pattern. It seems that in Mesoarchean time the Bundelkhand, Aravalli and Western and Eastern Dharwar Cratons were parts of the Kenorland Supercontinent, rather than one block.
