Abstract: The Lower Silurian Series in the Chuandongnan-Qingbei area of China is well Groped out and contains abundant fossils. Theauthors have discovered reefs spreading in varying degrees on the layer through field trip and research Qijing Guanyinqiao ofChongqing, Puodu and its neighbouring area. Reef Typifing point, dune, strata grew into the middle-lower layer of Shiniulan for-mation (equal to middle llandovery ).Reef-building biota is mainly composed of Tabulata，Tetracorallia，Stromatoporida.Biodetritus bank and knotty limestone formed reef bottom. Reef growing and spreading was restricted by palaeoenvironment. Theshallow slope zone nearing Qianzhong uplift is favorable to reef development.
