Abstract:

Organic reefs in Early-Middle Silvrian, NW Sichuan, are small patch reefs on bioclastic banks in offshore continental shelf environment dominated by terrigenous sediments. The bioclastic banks are formed by storm action. The development of organic reefs is influenced by taphonomic feedback process. The input of massive terrigenous sediments and the excess of terrgenous nutrients are the major factors to control their development.
