Indian Geological Sequences: Salient Features and Major Events focuses on the first ever differentiation of the entire Indian record into a five tier hierarchical succession of geological sequences - five giga to 12 mega to 25 1st order to 68 2nd order to over 100 3rd order ones as its basic skeleton.

Indian Geological Sequences: Salient Features and Major Events focuses on the first ever differentiation of the entire Indian record into a five tier hierarchical succession of geological sequences - five giga to 12 mega to 25 1st order to 68 2nd order to over 100 3rd order ones as its basic skeleton. Using the developed grid of sequence timelines, the diverse inter-disciplinary geological manifestations on the broad tectono-stratigraphically homogeneous supra-region of GTM (Gondwanian Tethyan Margin from Arabia to Australia) have been mutually integrated towards chronicling of events with precision never ever realized earlier. The giga-sequences GS-I to GS-IV comprising eight mega-sequences MS-I to MS-VIII deal with the Precambrian in brief. GS-V (¬ 635 ma onward) MS-IX (¬ 635-444 ma) and MS-XII (¬ 61.6 onward) include orogenies while MS-X (¬ 444-259 ma) and MS-XI (¬ 259-61.6 ma) are dominated by dismemberment tectonics. The prime focus is on the correlation of events across scores of sedimentary basins from outcrop to subsurface, onshore to offshore, marine to non-marine, shallow to deep water, plant to animal, micro to macro-fossils, and Proto-Paleo-Neotethys to Indian Ocean. Among the major Phanerozoic events time precised are the ¬ 500 ma Acantha Zone mega MFS accretion of the then alien TH to the Indian margin, and the ¬ 50 ma P8 Zone mega MFS impingement of India on Asia while the important dismemberment events include the ¬ 159 ma late Middle Oxfordian Orientalis Zone Schilli Subzone 1st order MFS initiation of the Indian Ocean which culminated in steps with oceanic separation of Sri Lanka from Antarctica at the ¬ 107 ma early Middle Albian Dentatus Zone mega MFS, ¬ 90 ma 1st order SB initiation of separation of Madagascar so also of Mascaranes basin, NER, Central Indian basin, Wharton basin, separation of Greater Seychelles from India at the ¬ 64.5 ma intra Danian 2nd order Quadratus Zone MFS and ¬ 24 ma Complanata Zone MFS thrusting due south of Greater Himalaya upon Lesser Himalaya. Indian Geological Sequences: Salient Features and Major Events is a valuable reference for researchers and scientists in the field of Earth Sciences.
Familiar with academic frameworks in the developed world, Prof. Krishna is an internationally acclaimed Geo-Science Educationist, University Teacher and Researcher with over five decades of experience of administering teaching, research, and mass awareness collaborative programs in Earth Sciences. Over the last five decades, he has published about 100 research papers inclusive in NATURE, chaired conferences, delivered invited lectures, realized collaborative researches during his umpteen stays across the globe in over 60 reputed Geo-Science institutions of the Americas, Europe, Asia, Africa, Arabia, and Australia. Formally relinquishing the Banaras Hindu University in 2011 as Professor and Head of its Centre of Advanced Studies in Geology, he has even more actively and passionately carried forward his academic pursuits. Prof. Krishna in 2017 authored--The Indian Mesozoic Chronicle: Sequence Stratigraphic Approach published by SPRINGER. Enthused with response and support from a large cross-section that the book received, Prof. Krishna, now presents unto the Geo-Science community across the world his fresh sequence stratigraphy-based venture with yet larger canvass and time-span--The Indian Geological Sequences: Salient Features and Major Events--brought out by ELSEVIER as an innovative high-resolution insight into the integrative understanding of the geodynamic evolution of the Gondwanian Tethyan Margin from Arabia to Australia with focus on the Indian subcontinent.
