Discovery of a Cataclastic Shear Zone from the East Dharwar Craton, India

Abstract

A new cataclastic shear zone, exposed between Rangapur and Shivannaguda, from the East Dharwar Craton, is reported here for the first time. The shear zone is characterized by breccias, cataclasites, mylonites and intense fracturing suggesting that the rocks are subjected to brittle-ductile transitional deformation. Image interpretation and preliminary field observations suggest that the shear zone stands out as a potential field example for demonstration and future geoscientific investigations.
