Recent Benthic Foraminiferal Biofacies and its Environmental Significance in the Goguleru Creek, Coastal Andhra Pradesh

The Goguleru creek is a supralittoral brackish water creek located between Krishna and Godavari Delta in coastal Andhra Pradesh. The creek is divisible into the two domains of drain and lagoon. R-Mode cluster analysis was carried out on benthic foraminiferal total population for the months of December 1988 (Winter) and May 1989 (Summer) and four and three major biofacies were recognized respectively. Two of the biofacies are dominated by agglutinated forms while the others are dominated by Ammonia and Asterorotalia. The distribution of these biofacies corresponds to characteristic sub-Environments present in the creek, such as marshy, brackish and open-Sea near shore/Beach. Such studies may help to recognize similar paleoenvironments.
