Timing of intraplate deformation, northeastern Indian Ocean

Seismic stratigraphy and DSDP and ODP drilling have demonstrated that two unconformities, of early Eocene and latest Miocene age, can be traced over much of the northeastern Indian Ocean. The Eocene event was a major hiatus in sedimentation following collision of India with Asia, and was the time of termination of deposition of a continental rise off the east side of India and the initiation of proximal Bengal Fan deposition. The Miocene event was the onset of north-south compression in the Indian plate during rapid uplift in Tibet and the Himalayas.
