中国南方二叠纪海绵礁的成礁模式

广泛发育于我国南方碳酸盐岩台地区的二叠纪生物礁，其中绝大多数属于海绵生物礁。从该地区二叠纪海绵生物礁的内部成礁因素分析，即从主要造礁生物－钙质海绵和钙质藻类等的生物学和生态学特征、埋藏和保存特点等方面进行分析，提出了华南二叠纪海绵生物礁主要是由于其主要造礁生物钙质海绵和钙质藻类独特的生物学特征、生态学特征以及它们的共同作用所形成的。此模式与其它地质历史时期生物礁的成礁模式明显不同。

REEF BUILDING MODEL OF PERMIAN SPONGE REEFS IN SOUTH CHINA

The Permian organic reefs, most of them belong to sponge reefs, which are widely developed in the carbonate platform areas of the South China. In view of the fact that many researchers study the reef building model of the sponge reefs from the outer reef building environmental factors, the authors studied and analyzed in this paper the inner reef building factors, which are biological and ecological features, buried and preserved properties of calcisponges and calcareous algae being of main reef building organisms. And then we suggest the algae sponge's reef building process or model of the Permian sponge reefs in the South China. This model is different from that of the other organic reefs in the geological history.
