Abstract
Biostratigraphic Zones Bb. Bz. H. I-V distinguished in C14 dated Peat, peaty clay sediments above arid, Barren zone have identified distinct environment of deposition as fresh water mixed brackish water to shallow marine to brackish water mangrove swamp, brackish water mixed fresh water swamp followed by colonization of non-littoral species to fresh water swamp during Holocene in the Bengal basin, India in chronological succession. The successive phases of depositional environment have identified the events of sea level rise, marine transgression and sea ward movement of the sea. The unique database has explored successive changes in the geomorphology of South Bengal from upland dry to marine deltaic environment to fresh water upland condition.
Highlights
Late Quaternary research has attracted considerable attention of the scientists since late 20th century to acquireHow to cite this paper: Sen, P.K. and Banerjee, M. (2016) Holocene Biostratigraphic Zones Corresponding Litho-Chronostratigraphy, Environment of Deposition and Successive Changes in the Geomorphology of Bengal Basin, India during Last 10,000 Years
The biozones Bb.Bz.H.I-V above Barren zone have revealed the pattern of ecological and geomorphological changes that occurred in the lower part of Bengal basin lying in the western part of the Bhagirathi Hinge (Figure 1) during Holocene
Distinct change is revealed in the environment from upland arid condition to marine, deltaic to fresh water condition affecting the change in the geomorphology of south Bengal within last ten thousand years as summarized in the following (Figure 12)

(2016) Holocene Biostratigraphic Zones Corresponding Litho-Chronostratigraphy, Environment of Deposition and Successive Changes in the Geomorphology of Bengal Basin, India during Last 10,000 Years. Multidisciplinary study of diverse biological remains of diverse eco-system including mangrove in the c14 dated Holocene sediments has generated rich data revealing the ecological changes that occurred in the Bengal basin, India during last ten thousand years. The change in the environment of deposition identified through analysis of Biostratigraphic zones Bb. Bz.I-V above Bb.Bz. Barren zone is discussed taking into consideration the litho-stratigraphic and chrono-stratigraphic succession. The biostratigraphic zones have revealed the successive changes in the geomorphology of the south Bengal basin during last 10,000 years
