Description :
The organic deposits derived from the mangrove swamps form reliable stratigraphic makers within the Late Quaternary sequence of Kerala-Konkan Basin. Three generations of such deposits have been identified. Pollen analyses confirm that the deposits are mostly derived from the mangrove vegetation. Peat accumulation during the period 40,000-28,000 C 14 yr B.P. can be correlated with the excess rainfall 40-100% greater than modern values, of the Asian summer monsoon. The palynological data of the mangrove deposits obtained and their utility on palaeomonsoon studies of west coast of India mainly from Kerala-Konkan Basin heve been addressed in this paper.
