Abstract
This research is interesting because the Delta Plain in Sangatta, East Kalimantan from ancient to modern deltaic washout. The deltaic environment in the Sangatta area has prograded from west to east from the Early Miocene to the Pliocene, this is referred to as the ancient delta plain. Rapid progradation is mainly seen in the delta plain, causing intensive delta development, resulting in varied coal seams and coal bearing sediments consisting of channel deposits, overbank deposits, levee deposits and splay deposits, are deposited in Marsh Habitat environments. Each deposit changes vertically or laterally, this change is caused by lateral channel moving (migration) followed by rapid progradation. Modern delta plain from the aerial photos is seen as a flood plain deposit (swamp) as product of a river channel (fluvial) which ends up on the coast. The process of channel laterally migration causes coal splitting and washout. Simple Splitting occurs in the Middle Seam to become the Middle Upper Seam and Middle Lower Seam, while river channel erosion (washout) occurs in the Middle Lower Seam. Keywords: progradation, channel, washout, swamp.
