摘要
The preservation of Ediacaran fossils in China are grouped into five preservational modes : phosphatization , kerogenization , pyritization , silicification and clay replication.Five representative fossil preservational modes identified in Ediacaran fossil Lagersttten in China and their tempo-spacial distribution patterns and taphonomic mechanisms are reviewed in this study.Our study indicates that kerogenization is the primary preservational style amongst the five taphonomic modes ; phosphatization and silicification are widespread ; and pyritization and clay replication are relatively rare in China.The kerogenization and pyritization are usually present in sandstones and mudstones ; while the phosphatization and silicification often occur in phosphorite , chert , and phosphatic and siliceous nodules.Several fossil preservational modes usually occur in the same fossil Lagersttte , resulting in multiple taphonomic pathways.Further integrated studies are required to test how the multi-preservational modes take place during the Ediacaran Period.
