Neogene planktonic foraminifera of the western tropical Indian Ocean
Neogene calcareous sediments were recovered at 12 sites in the western Indian Ocean (Table 1). Approximately 1000 10-cm**3 samples, at a sampling interval of about 1.5 m, were collected from one hole at each site for planktonic foraminifer analysis. Samples were washed through a 63-?m mesh sieve. Dr...
