Geologically, the ancient city of Hampi falls on the Archean Dharwar craton in an area composed of volcanosedimentary greenstone contained in a larger region of peninsular gneiss and granites. These are dated to be in the Archean period somewhere between 3.3 and 2.7 billion years old (Moyen et al., 2003).

Many of these small hillocks hosting Archean rocks belonging to the Dharwar Craton are seen outside Tumkur, a city in Karnataka around an hour and a half outside Bangalore.
