摘要/Abstract

摘要：

21 species foraminifera, including in 14 genera were encountered from 39samples of core PC10, which were drilled in the Bransfield Strait of Antarctic Peninsula. They are divided into 3 assemblages as follow: 1. Siliceous shell assemblage; 2. Calcareous shell assemblage; 3. Mixed shell assemblage. The Siliceous shell assemblageoccurred in normal deep-sea, with weaker water dynamic condition. The Calcareousshell assemblage was formed by turbidity now, while the Mixed shell assemblage represented intense to weaker water dynamic condition. It changed from warm to cold towarm during the late Quaternary.
