| Abstract: | This paper studies some Late Ordoyician reefs developed in Sanqushan Formation at Wangjiaba, Yushan County, Jiangxi Province. Three communities can be recognized in these patch reefs. They are 1). Sibiriolites jiangxiensis community, 2). Fletcheriella grandis-Pachystylostroma community, 3). Trocholites-Encrinuroides community. Community 1 occupies the reef-base facies. Community 2 covers the reef-core facies and community 3 belongs to level bottom community. Six guild types have been recognised in the patch reefs. They are framing guild, baffling guild, binding guild, destroying fuild, dwelling guild and cementing guild. |
