Sulphur enrichment in a sediment core from the central western continental margin of India

Abstract

Anomalous sulphur values in relation to organic carbon have been found in the sediments of a core collected from the central western continental margin of India. The relationship between organic carbon and sulphur is similar to that of the sediments deposited in anoxic environment. Our study indicate that the excess sulphur is mainly due to the addition of sulphides from the shallow regions by mass sedimentation processes rather than water column sulphide formation as observed in anoxic environment
