Publisher's Synopsis
Tectonics of the Eastern Continental Margin of India presents the different aspects of a passive margin such as its evolution, tectonics, and associated hazards, taking the Eastern Continental Margin of India (ECMI) as a case study. It discusses the passive margin and focuses on its origin, morphology, structure, and exploration potential; describes the major structural lineaments delineated from the geophysical data over the ECMI; and attempts to explain the geodynamic evolution of this passive margin. A preliminary estimate on the seismic hazards associated with ECMI is also presented in the book.
