Narayana, A.C., 2007. Peat deposits of the west coast of India: implications for environmental and climate changes during late quaternary. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 683 – 687. Gold Coast, Australia, ISSN 0749.0208

Two boreholes (viz., one in a lagoon and the other in a paleo-delta), drilled in the coastal land of south-western India penetrated layers of peat. Radiocarbon ages and pollen analysis of these deposits were carried out. Radiocarbon dating of samples of peat suggested ages as 8,460 yr and >40,000 yr B.P. Pollen analysis of peat samples of BH-1 yielded pollen assemblages belonging to the family Rhizophoraceae and Mallotus. Peat samples of BH-2 with C-14 age of 8460 yr B.P. reveal the presence of mangrove forest comprising Avicennia and Kandalia. The evidences strongly suggest possible existence of various mangrove forests under different environmental conditions.
