东太平洋CC区1787号岩心的微体化石及地层层序
Microfossils and stratigraphic sequences in the Core 1787 of CC area from the East Pacific Ocean
-
摘要: 本文根据1994年“向阳红09号”调查船自东太平洋CC区获取的1787号岩心(8°23.49'N、141°56.13'W,水深为5070m,岩心长为810cm),对其中的微体生物(放射虫、硅藻、硅鞭毛藻、抱粉)地层进行了初步探讨.对于不同的分析样品,采取了不同取样间隔,如放射虫每隔5cm取样1个,共采样162个;硅藻每隔8～9cm取样1个,共采样82个;孢粉每隔20cm取样1个,共采样34个.
