CALCAREOUS NANNOFOSSIL BIOSTRATIGRAPHY AND ITS PALAEOENVIRONMENTAL IMPLICATIONS FROM MANNAR BASIN, SRI LANKA

摘要

Present study evaluates the record of calcareous nannofossils from the deep ocean calcareous sediments recovered as drill cuttings from CLPL-Barracuda G1/1 Petroleum Exploration Well drilled at Mannar Basin. The well site is 68 km away from the North Western coastline of Sri Lanka at a latitude of 08 degrees 20' 34.460 '' N and a longitude of 79 degrees 09' 39.378 '' E. Randomly selected 20 samples were studied covering the depth from 2,145 m - 3,405 m. Each sediment sample represented a depth of 10 m.
