Silicoflaggelates from ODP Leg 120 on the Kerguelen Plateau@en

The biostratigraphic distribution and abundance of Eocene to Pleistocene silicoflagellates is documented from Ocean Drilling Program Leg 120 Holes 747A, 748A, 748B, 749B, and 751A on the Central Kerguelen Plateau. Well-preserved silicoflagellates are reported here from the middle Eocene Dictyocha grandis Zone to the Pleistocene Distephanus speculum speculum Zone. Assemblage diversity and abundance is variable, with many intervals either barren of silicoflagellates or containing only limited numbers.本数据集记录了凯尔盖朗海台中部（Central Kerguelen Plateau）大洋钻探计划（Ocean Drilling Program，ODP）第120航次747A、748A、748B、749B及751A钻孔中，始新世至更新世硅鞭藻（silicoflagellates）的生物地层分布与丰度特征。本次研究报道了从中始新世强壮网鳞藻（Dictyocha grandis）带到更新世星冠藻（Distephanus speculum speculum）带的地层中，保存完好的硅鞭藻化石。硅鞭藻组合的多样性与丰度存在明显波动，多数层位要么无硅鞭藻产出，要么仅含少量个体。
