| 摘 要： | 以三叶虫化石带的划分对比为时间标尺，通过对华北地台东部山东和辽宁复州湾8个中寒武世剖面广泛发育以Epiphyton，Renalcis和Girvanella类群落建造的微生物礁时空分布研究表明：曾经有5次主要的造礁期，它首现的最低层位是山东长清崮山徐庄阶顶部Bailiella—Lioparia带，而后在张夏期以此为核心向东、东北、东南扩展，至张夏阶顶部的Demesella-Yabeia带规模达最大。

| Abstract: | According to the time scale of trilobite biozones, temporal and spatial distribution of microbiolitic buildups constructed by Epiphyton, Renalcis and partly Girvanella community is worked out based on 8 sections in eastern North China Craton, Shandong and Liaoning. Five cycles of microbiolitic buildups occurred in this area. The lowest microbiolitic reefs appeared in the Bailiella Lioparia Biozone, the top of the Xuzhuang Stage. But it is limited to the Gushan, Changqing area. Reefs spread around Changqing to each direction during the Changhia Stage. In the Damesella Yabeia Biozone, the top of the Changhia Stage, the distribution of reefs reached the climax in scale and almost covered whole epicontinental sea of eastern North China Craton. |
