Content: 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.

Note: Indian Geological Sequences: Salient Features and Major Events uses sequence stratigraphic concepts to innovatively differentiate the entire ~4500 ma Indian geological record into four giga, twelve mega, 25 first order, over 65 second order, and over one hundred third order isochronous tectono-stratigraphic sequences spread across India and its neighbors. The book's focus is on the youngest giga-sequence of Terminal Neoproterozoic–Cenozoic span and sequence surface timelines ~635 ma onward (two for each sequence: one SB and one MFS) for chronicling the high-resolution geodynamic evolution of India and the surrounding countries between Arabia and West Australia.
