Geography of Bangladesh
Ganges River Delta

The Geology of Bangladesh is affected by the country's location, as Bangladesh is mainly a riverine country. It is the eastern two-thirds of the Ganges and Brahmaputra river delta plain stretching to the north from the Bay of Bengal. There are two small areas of slightly higher land in the north-centre and north-west composed of old alluvium called the Madhupur Tract and the Barind Tract, and steep, folded, hill ranges of older (Tertiary) rocks along the eastern border.[1]

The downwarping of the basement rocks under central and southern Bangladesh result from the pressure of sediments that have been accumulating since the Cretaceous period, mostly a large quantity of carbonate. In the Late Eocene epoch the conditions in the Bay of Bengal changed and these deposits ceased.[2]
