Abstract

A study has been conducted to image seismic scatterers beneath the Gauribidanur (GBA) array in the Precambrian shield of southern India. Short period digital data from teleseisms and regional events recorded over the 20-station L-shaped array were used to image seismic scatterers beneath the array employing a semblance technique. The results indicate a zone of dominant scattering encompassing the crust in a region west of GBA, coinciding with a large NS elongated granitic intrusion believed to be Precambrian suture zone between the east and west Dharwar craton.
