Origin and Evolution of the Deep Continental Crust

This book provides the recent research in the field of Deep Continental Crust in India. Several new data sets on the interesting aspects of petrology and geochemistry of the Indian lithosphere and glimpses of the regional geology and geodynamics of parts of the Indian Shield have been provided.

It includes articles on sapphirine bearing granulites from Karur, amphibolites from Hutti-Maski Gold mine, granites from Varshanadu and mataconglomerate-quartzite from Malvan which provide vital clues to the Pre Cambrian evolution of South India. The articles from Bastar Craton are related to felsic magmatism Dongargargh granites from Gadchiroli and the Bijli rhyolite while the Paleoproterozic high-MgO dykes represents the basic magmatism from this craton. Studies related to Kimberlite magmatism from the Wajrakarur and Manipur kimberlite, The Jungel valley alkaline lamprophyre, the dyke-flow co-relation and fluid inclusions from the Deccan Traps, and xenolith bearing host alkaline magmatism from Kutch provide important clues to the evolution of the sub-continental lithospheric mantle (SCLM). The possibility of the Lonar impact glass as potential natural analogue for nuclear waste galss is also discussed. The paleomagnetic data of some litho-tectonic units from the Indus Suture Zone, Ladakh also provide insight into the paleo-latitude reconstruction of India. The book thus serves as a useful and up-to-date reference for students, academicians and researchers.
