摘要
A shallow sedimentary core (PL-1) of 12.5m length was analyzed for lithological, paleontological and radiocarbon dating. The core shows fairly uniform lithological (sandy) composition and foraminifera. The marine molluskan shells at 12m depth provide 3660±80 yr BP age by 14C isotope dating. This age in correlation with timing of mid-late Holocene sea levels, facilitates to infer that the Pulicat lake has emerged during 2nd high stand sea level (4330±2500 cal years BP) in late Holocene.
