中文摘要：

埃迪卡拉纪化石保存方式具有多样性，包括：磷酸盐化、有机碳质压膜、黄铁矿化、硅化、以及粘土矿物交代。文中综述了以上各种化石保存方式在地层中的时代分布规律、埋藏特征和形成机理，并分析了这些类型的化石库在我国埃迪卡拉纪地层中的地理分布规律和埋藏学意义。分析结果表明：华南埃迪卡拉纪化石库的保存方式主要以有机碳质压膜为主；磷酸盐化和硅化保存方式分布较广；黄铁矿化和粘土矿物交代方式在中国埃迪卡拉纪地层保存较少。有机碳质压膜、黄铁矿化多见于粉砂岩、泥岩中；磷酸盐化、硅化多出现于磷块岩、燧石层或碳酸盐岩的磷质、硅质结核中，化石多为微体化石。另外，多种化石保存方式常常同时出现在同一化石库中，形成复合式的保存模式。

英文摘要：

The preservation of Ediacaran fossils in China are grouped into five preservational modes： phos- phatization, kerogenization, pyritization, silicification and clay replication. Five representative fossil preservational modes identified in Ediacaran fossil Lagerstgtten 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; phosphatiza-tion 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 Lagerstatte, resulting in multiple taphonomic pathways. Further integrated studies are required to test how the multi-preservational modes take place during the Ediacaran Period.
