Abstract
The distribution of calcium carbonate in Visakhapatnam shelf sediments is controlled by the mollusca shells and shell fragments and foramini fera. The high concentrations near the river mouths are indicative of the detrital contribution also. The concentrations decrease from top t o sub-bottom levels due to more dilution by the detritus from the adjo ining area and less deposition of non-detrital calcium carbonate in th e geological past.
