The lithosphere beneath the Indian shield : a geodynamic perspective

The lithosphere beneath the Indian shield : a geodynamic perspective / Ashoka G. Dessai.

This book explores the geotectonic evolution of the lithosphere beneath the Indian Shield, which comprises a collage of cratons variously bounded by mobile belts and palaeo-rifts. The lithosphere beneath these is fairly thin compared to other cratons worldwide, petrologically varied and shows consid...
