The Lithosphere Beneath the Indian Shield: A Geodynamic Perspective

The book explores the geotectonic evolution of the lithosphere beneath the Indian Shield, which is composed of cratons bounded by mobile belts and palaeo-rifts. It has been subjected to repeated magmatic episodes from Proterozoic to Palaeocene, and the thermotectonic influence on constituent cratons is variable. It provides a petrotectonic perspective on the deep crust and shallow mantle from direct samples brought up as xenoliths and offers insights into the spatio-temporal evolution of the Indian Shield.

The Indian Shield, a mosaic of cratons surrounded by mobile belts and palaeo-rifts, is the focus of this captivating book. The lithosphere beneath these cratons is remarkably thin compared to other cratons worldwide, displaying a diverse petrological composition and significant variations in thickness with depth, both within and among cratons. Furthermore, it has endured the influence of numerous magmatic episodes spanning from the Proterozoic to the Palaeocene, exerting varying impacts on different regions of the shield. The thermotectonic influence on individual cratons varies depending on their evolutionary history.

This book delves into the profound impact of successive tectonomagmatic events on the evolution of the deep crust and shallow mantle, as revealed through the insightful xenolith window. It offers a petrotectonic perspective on these crucial components of the Earth's structure, drawing from direct samples retrieved as xenoliths from deep lithologies. By integrating the results of petrological studies of deep lithologies and geophysical investigations, the book provides a comprehensive overview for students, researchers, academics, and professionals. It sheds light on the physico-chemical and thermal structure of the lithosphere across diverse geotectonic settings and offers valuable insights into the spatio-temporal evolution of the Indian Shield.

This book serves as a valuable guide for critical thinking on the intricate subject of mantle differentiation, magmatism, lithosphere modification, and crustal growth over time. It empowers readers to gain a deeper understanding of the processes that shape the lithosphere and contribute to the formation of the crust upon which we reside. Through its comprehensive and interdisciplinary approach, this book offers a wealth of knowledge and insights that will captivate anyone with an interest in Earth sciences and geosciences.
