Abstract
Pseudotachylytes in granitoid rocks of the Bundelkhand craton are formed either by crushing dominated process or by pervasive melting. Microstructural observasions reveal that pseudotachylytes include three major varieties: pseudotachylyte-breccia, homogeneous pseudotachylytes and crushed pseudotachylyte. Size frequency diagrams of clasts show power law distribution pattern for crushing dominated pseudotachylytes and “left hand fall off” or curvilinear pattern for melt affected pseudotachylytes.
