摘　　要：分别对锦州大笔架山连岛坝J10钻孔及附近海域J3钻孔进行微体古生物分别进行丰度、分异度及主要属种组合进行分析,并对两个钻孔进行对比分析,划分出两个沉积阶段。研究结果表明:锦州大笔架山连岛坝附近海域沉积环境大致演化进程对应海侵时期,分为海侵过程开始和海水持续入侵两个阶段,逐步接近两个地区现今的沉积环境。The abundance, differentiation and species composition of J3 and J10 from the Stratum near mount Big Bijia in Jinzhou were analyzed. The two cores were compared. Two sedimentary stages were divided. The research results show that sedimentary environment evolution process of the Stratum near mount Big Bijia in Jinzhou is a transgression of sea. There are two stages in the transgression of sea. They were divided into transgressive process starts and seawater intrusion lasted two stages. It evolved into the sedimentary environment of the area gradually.
