Indian Geological Sequences: Salient Features and Major Events (Paperback) (ISBN-13: 9780128212707)

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 1^st order to 68 2^nd order to over 100 3^rd 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 (ｬ 635 ma onward) MS-IX (ｬ 635-444 ma) and MS-XII (ｬ 61.6 onward) include orogenies while MS-X (ｬ 444-259 ma) and MS-XI (ｬ 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 ｬ 500 ma Acantha Zone mega MFS accretion of the then alien TH to the Indian margin, and the ｬ 50 ma P8 Zone mega MFS impingement of India on Asia while the important dismemberment events include the ｬ 159 ma late Middle Oxfordian Orientalis Zone Schilli Subzone 1^st order MFS initiation of the Indian Ocean which culminated in steps with oceanic separation of Sri Lanka from Antarctica at the ｬ 107 ma early Middle Albian Dentatus Zone mega MFS, ｬ 90 ma 1^st 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 ｬ 64.5 ma intra Danian 2^nd order Quadratus Zone MFS and ｬ 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.
