Geological Evolution of the Precambrian Indian Shield

This book presents findings from research into the Precambrian history of the Indian shield obtained using state-of-the-art technology. It demonstrates a paradigm shift towards studying the Precambrian shield regions using petrological, geochemical, structural, metallogenic, sedimentological and paleobiological data from the rocks in the Precambrian shield area, and presents a collection of contributions on these diverse topics that help to reconstruct the Precambrian evolution of the Indian Shield.

Presents the latest research on the Precambrian evolution of the Indian shield Covers various aspects of geosciences, including paleobiology Includes comprehensive petrological and geochemical datasets
