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
A high-resolution chronostratigraphy was established for Holes 680B and 686B, drilled during Ocean Drilling Program (ODP) Leg 112 off Peru. The stratigraphy is largely based on oxygen isotopes of bent
