The chronostratigraphy, the calcareous nannofossil biochronology, and the biostratigraphy of the Miocene and Pliocene sediments retrieved during Leg 115 in the equatorial western Indian Ocean are presented and discussed. Most of the zonal boundaries of the standard 1971 zonation of Martini and the 1973 zonation of Bukry are easily recognized in these low-latitude sediments. We also comment on the secondary events that are proposed in the literature to improve the biostratigraphic resolution provided by the standard zonations.The study of calcareous nannofossil biostratigraphy and taphonomy of sequences from the Northern Mascarene Plateau area, which was drilled to investigate the Neogene history of carbonate flux and dissolution, indicate that the accumulation of carbonates in this area results from a complex interplay among carbonate bioproductivity, carbonate removal by chemical dissolution and mechanical erosion, and carbonate addition by mass and current transport. In spite of these drawbacks, major changes and trends in carbonate accumulation can be recognized, most of which, if not all, correlate with major steps in the evolution of the Neogene climatic system.

“…Berger and Roth (1975) state that calcareous nannofossils are as solution resistant as foraminifers. Other researchers, observing that nannofossils persist at relatively greater depths than foraminifers, suggest that calcareous nannofossils are more resistant to dissolution than foraminifers (Schneidermann, 1973). Recent experiments of Adelseck (1977) point out that tropical nannofossil assemblages may be less resistant to dissolution than the assemblage of larger planktonic foraminifers.…”

“…Recent experiments of Adelseck (1977) point out that tropical nannofossil assemblages may be less resistant to dissolution than the assemblage of larger planktonic foraminifers. The degree of dissolution increases not only with depth of deposition (Schneidermann, 1973;Berger, 1973), but also as a function of the content of organic matter in the sediments (Berger and Winterer, 1974). Thus, dissolution increases drastically in areas of high fertility, such as areas of up welling.…”

“…In pelagic environments calcareous nannofossil assemblages can be altered because of selective dissolution in the calcium carbonate compensation realm resulting in an increase in the relative proportion of solution resistant taxa (McIntyre and McIntyre, 1971;Schneidermann, 1973;Roth and Coulbourn, 1982). Calcareous nannofossil assemblages dominated by Watznaueria barnesae have been reported as indicative of oligotrophic or low fertility environments (Roth, 1989;Roth and Krumbach, 1986;Premoli Silva et al, 1989;Watkins, 1989;Erba, 1992).…”

C of ~5‰). However, a low enrichment of redox-sensitive trace elements indicates that the basin did not achieve anoxic conditions. The results also suggest that a shallower-phase of the basin, coeval with platform progradation, may have increased ventilation of the basin at the same time that heightened sedimentation rates and additional input of organic matter from terrestrial sources increased the burial and preservation rate of TOC in the sediment.
