The Bengal Depositional System is defined as the surface depositional environments and the underlying sediment accumulation extending from the alluvial, lacustrine and paludal sediments of the lower Ganges and Brahmaputra Rivers, across the Bengal Delta, the Bangladesh continental shelf and slope to and including the Bengal Fan. Together it is one of the greatest sediment accumulations in the modern world, and is comparable in volume to the great sediment accumulations of the geological past. The history of formation started with the Mesozoic breakup of Eastern Gondwanaland, the northward drift of India, its collision with the southern margin of Asia, rotation and bending of the western Sunda Arc, and the penetration of the Indian continental mass into southern Asia. During this history, the regional tectonics evolved and sources and provenance of the sediments changed with the ultimate uplift of the Tibetan Plateau and the Himalayas. (C) 2014 Elsevier B.V.

Rates of sediment accumulation and the amount of sedimentary fill in depocenters lying downstream of erosion in the Himalayas and Tibet can provide some insight into tectonics and geological history. The objective of this paper is to put on record the best estimates which are possible with existing data of the volume and mass of sediments, sedimentary rock and metasedimentary rock beneath the sea floor of the Bay of Bengal. The sedimentary section in the Bay of Bengal is divided into two parts: (1) Eocene through Holocene, sediments and sedimentary rocks which post-date the initial India-Asia collision: volume - 12.5 X 10(6) km3; mass = 2.88 X 10(16) t; this is most of the Bengal Fan, including its eastern lobe, the Nicobar Fan, plus some of the outer Bengal Delta; (2) Early Cretaceous through Paleocene, pre-collision sedimentary and metasedimentary rocks: volume = 4.36 X 10(6) km 3; mass = 1.13 to 1.18 X 10(16) t; these are interpreted as continental rise and pelagic deposits.
