Sea level varied throughout the geological past where eustatic and/or tectonic change played significant role in controlling the sea level. Unlike glacial and interglacial periods, no major sea level fluctuations
have been observed during mid-late Holocene period. Thus, reconstruction of local sea level history rather than accepting global sea level change
remains a challenge. Various studies have addressed mid-late Holocene sea level changes but only few could delineate the tectonic component involved
in it. Saurashtra coast provides an ideal platform to study Holocene land-sea interactions. The southern Saurashtra coast consists of extensive mudflats which can provide a continuous record of sea level change.
Sulphur isotope (delta 948;34S) has played a crucial role in constraining the biogeochemical cycle in modern environment and proven to be a valuable
tool in unravelling the early history of earth surface oxidation. The talk will address local tectonic event deciphered from sulfur isotopes
supported by productivity and redox proxies that resulted in local sea level change during mid-late Holocene period.
