Textural and physicochemical studies of innershelf sediments off Gangolli, west coast of India

Abstract

Textural and physico-chemical studies such as grain size, organic carbon, Ca and magnetic susceptibility of sediments of the innershelf off Gangolli have been carried out. The sediments are clayeysilt and siltyclay in texture. They are well-sorted, negatively skewed and leptokurtic. Multigroup descrimination analysis suggests that these sediments are derived from shallow marine origin by saltation and suspension. The amount of organic carbon and Ca increases with the depth. Organic carbon has positive correlation with Ca. The magnetic susceptibility (Xm) shows high values and has the positive correlation with mean size (Mz).
