Geology of India. Volume 2 / Геология Индии. Том 2

A phenomenal growth has been achieved in our understanding of the Geology of India since India's Independence through the efforts of the Geological Survey of India and several other State Surveys, exploration agencies, research organizations, universities, institutes and scientific societies. Many of our earlier concepts of geology in relation to structure and tectonics, stratigraphy and sedimentation, magmatism and metamorphism, and metallogeny and mineral deposits have undergone drastic changes with larger inflow of data, synchronising with the evolving global concepts of earth processes. New dimensions have been added to Indian stratigraphy by detailed geological mapping on the one hand and through geochronology and to a limited extent geophysics and geochemistry. The need for a comprehensive, nevertheless succinct account of the geology of India, keeping in view the above developments, has been keenly felt and a positive step has been taken by the Geological Society of India in entrusting to two of our outstanding earth scientists, Prof. R. Vaidyanadhan and Dr. M. Ramakrishnan, the task of addressing this need. Professor Vaidyanadhan hails from an educational stream from the Andhra University and is widely known for his expertise in geomorphology and a capability for incisive synthesis and review. Dr. M. Ramakrishnan has several decades of dedicated field work in different parts of the country to his credit under the banner of the Geological Survey of India and in guiding streams of younger scientists in geological mapping and interpretation. Both the authors have published widely quoted papers of lasting value. They served the Geological Society in the challenging task of being successive editors to the Journal of the Society and have established editorial capabilities. It goes to the credit of these two earth scientists that they, in the present two volumes, provide an exhaustive and commendable synthesis of Indian geology, covering the major recent advances. They have thereby generated, perhaps, the almost up-to-date and authentic publication on the subject now available. <...>
