摘要
辽东半岛南部早古生代地层发育，其中馒头组—冶里组的沉积过程，具有完整的陆源碎屑岩—碳酸盐岩堆积特点。从层序划分、沉积环境演化、古气候变迁等方面分析，馒头组—冶里组反映了一个完整的碳酸盐岩台地的发展过程，可划分出准备阶段（形成碎屑岩垫板）、生长—发育阶段（形成碳酸盐岩缓坡）及衰亡阶段（发育白云岩盖层）。
The early Palaeozoic strata developed well in the south of Liaodong peninsula,in which Mantou F. Yeli F. strata had a complete accumulation feature from terrigenous clastic rock to carbonate rock. On the aspects of stratigraphic sequence subdivision, sedimentary environment evolution, paleoclimate change, the paper expounded the evolution stages of Mantou F. Yeli F. carbonate tableland: the preparing stage(the forming of clastic rock cushion), growing developing stage (the forming of carbonate rock gentle slope) and the declining stage (the developing of dolomite cover).
