    Abstract
    Sediment samples collected from dunes, beaches (Calangute, Baina and Colva) and nearshore environments along the coast of Goa, have been analysed for their carbonate content. The results show the presence of very high carbonate content (60-90%) in the foreshore regions of individual beaches whereas low CaCO sub(3) (less than 20%) in the dune and backshore areas of these beaches and adjoining nearshore environs up to 10 m isobath. The observed spatial distribution shows the occurrence of modern carbonate sediments of skeletal origin. Carbonate content of the beaches shows marked seasonal variations and closely follows the seasonal cyclic changes in beach morphology
