Leg 116 drilled the abyssal plain south of the Bengal deep-sea fan, primarily to understand the erosional history of the Himalayas and the character of oceanic-floor tectonism in the area.
The Leg 96 program confirmed extremely rapid rates of deposition on the mid fan (11 meters per thousand years at a distance of nearly 500 kilometers from the river mouth) and that large-scale landsliding also provides major contributions to deep-sea fan sequences.
Migration of deltaic lobes and the associated deep-sea fan deposits result in a complex lateral and vertical distribution of sandstone bodies of the Forbes Formation in the Sacramento Basin.
