Structure and Tectonics of Southern Asia

To fully understand the petroleum systems of South Asia you must first have an appreciation of the breakup history of Gondwana, the subsequent fragmentation of the Indian Plate during its drift phase and its collision with Eurasia.

Key to the scientific rigour of this report is the mapping of the structural framework against data, including Getech’s best available gravity and magnetic data. This in turn constrains the plate model, which is also developed in the context of Getech’s Global Plate Model to eliminate boundary effects. This report demonstrates the need for this approach as its findings have an impact over a much wider area.

This Regional Report investigates…

…the crustal nature of India’s neighbouring plates (e.g. the 85°E, Lactadive and Laxmi Ridges) and the impacts on models for Gondwanan breakup.

…a more satisfactory displacement between India and Madagascar across the Vishnu Fracture Zone.

…neotectonics as a constraint to plate modelling.

…the collision history of India and Eurasia.

…the timing of the Deccan Traps relative to basin forming events.
