Depositional Environments of the Binge Bay Near Karwar, West Coast of India

A large part of the area of the Binge Bay is floored by well sorted, medium to fine sand. The mean size of the sediments generally decreases with increasing depth and distance from the land. Variation in skewness from the Anjidiv Island to the middle of the Bay can be related to the mixing of two or more grain size populations in various proportions. An overall decrease in the weight per cent of total heavy mineral contents also is observed from the beach to the middle of the Bay. Fine muddy sediments are found in the regions of the main bathymetric low. Such variations occur as a result of decrease in velocity of the transporting tidal currents. The sign of the skewness is sensitive to the environment.
