Abstract

An improved shear wave velocity \((V_{\mathrm{s}})\) structure of the lithosphere of peninsular India using the surface wave tomography from the ambient noise and earthquake waveforms suggests its bipolar character. While most of the geological domains of India are characterised by a uniform lithospheric mantle of \(V_{\mathrm{s}} \sim 4.5~\hbox {km/s}\), the three cratonic regions, eastern Dharwar, Bastar and Singhbhum, hosting most of the diamondiferous kimberlite fields, show significantly high \(V_{\mathrm{s}}\) of 4.7 km/s and above in their lower lithosphere beyond \({\sim } 90~\hbox {km}\) depth. The higher velocity could best be explained by the presence of diamond and/or eclogite along with peridotite in mantle. This unique relationship suggests the regional seismic image of lithosphere as a guide for exploration of diamonds.
