- •
Refraction velocity models show a sedimentary cover of 13 km minimum beneath the shelf and 7 km minimum beneath the deep ocean.
- •
The crust is thinned continental crust, 10–20 km thick.
- •
The thinned continental crust is intruded by volcanics, sills and SDRs.
- •
Seismic velocities of 7.4 km/s found at the base of the crust is interpreted as magmatic underplating.
- •
The thinned continental crust extends from 19°N (northern Bay of Bengal) to 25°N (Shillong Plateau).
