Abstract
We present 2-D shallow P- and S-wave velocity models ( and ) using ray-trace inversion of firstarrival traveltimes picked for the wide-angle 3-C seismic data acquired along the 200 km long E-W trending profile in the Western Dharwar Craton (WDC) of southern India, which traverses across major shear zones like Chitradurga Shear Zone (CSZ). The 2-D velocity models have been constrained to a maximum depth of 15 km mainly confined to the upper crust of this highly complex and oldest (3.2
