Planktonic foraminifera communities at DSDP Holes 94-608 and 94-610

Thirty-one core-catcher samples from the middle Eocene to middle Miocene at Site 608 and 13 core-catcher samples from the lower to middle Miocene of Site 610 have been examined for planktonic foraminifers. Stratigraphic ranges have been established at both sites and the sequence divided into zones. Zonal markers and other datum events are correlated with the most recent time scale.

本研究对608站位中始新世至中新世中期的31份岩芯捕集器（core-catcher）样品，以及610站位早中新世至中新世中期的13份岩芯捕集器样品，开展了浮游有孔虫（planktonic foraminifers）鉴定分析。现已在两个站位确立了地层延限序列，并将该沉积序列划分为若干生物地层带；各生物地层带的标志化石及其他基准事件均与最新地质年代标尺完成了对比校准。
