Here's a breakdown:
* Dharwar Craton: This is the primary location for Dharwarian rocks. It spans across parts of Karnataka, Andhra Pradesh, and Maharashtra.
* Peninsular Shield: The Dharwar Craton is a part of the larger Peninsular Shield, which covers most of the southern and central India. This shield is known for its ancient and metamorphic rocks.
* Granites and Gneisses: These are the dominant rock types in the Dharwarian formations. They are formed through intense heat and pressure, reflecting the tectonic activity of the Archean era.
While the Dharwarian rocks are primarily found in the Dharwar Craton, they can be found in other parts of the Peninsular Shield, as well. However, the Dharwar Craton is considered the "type locality" for these rocks, meaning it's the place where they were first identified and studied.
