The Quaternary sediments in the studied area can be divided into: (a)qollovial of basement rocks, (b)fine-grained of mass flows deposits, (c)coarse-grained of mass-flow deposits, (d)marine sediments, (e)beach deposits, (f)floodbasin deposits, (g)young marine sediments, and (h)marine Recent sediments. Furthermore, the Quaternary sediment consists of 2 (two) depositional cycles namely west Karimata cycle (SKB.1) and west Karimata cycle 2 (SKB.2).The development of the Quaternary sediments and basin fill in the research area was influenced by global events. Changes in climatological conditions between more humid and more dry, and relative sea-level changes affect marine and coastal depositional environments were included by global changes. The style of the mass flow deposits, is primarily the result of the palaeoslope on the basin, and lateral and vertical changes of environment systems were inflenced by regional or local condition of Sundaland character.
