中文摘要：
埃迪卡拉纪（震旦纪）陡山沱期是Rodinia超大陆裂离的重要地质时期,是多细胞生物起源和发展的重要转折时期和磷质聚集时期,也是化学、气候和环境变化的剧烈时期。液化岩脉、液化角砾岩、脉化变形构造、以及阶梯状层内断层等磷质震积岩的发现,表明扬子地区在陡山沱期晚期至少发生过两次以上的地震事件。地震构造运动将地球内部积累能量快速地释放,可能是磷质来源和热水活动一种重要的方式或通道。海水中磷等无机营养盐分的增加,海水温度的升高,有利于多细胞生物的起源和发展,同时多细胞生物的繁盛又有利于磷的聚集。
英文摘要：
The Doushantuo Period of the Ediacaran （Sinian） is not only an important epoch of the origin and development of the mulicellular organisms and the accumulation of phosphates, but also an important epoch of the Rodinia Supercontinent cracking and a tempestuous epoch of the chemical, climatic, and environmental changes. The discovery of the phosphorus seismites, including liquefied vein, liquefied breccia, liquefied deformation structure, and fault-graded, indicate that the earthquake event happened at least two times in the Yangtze area during the late Doushantuoan. The seismotectonism caused the release of energy accumulated within the Earth. It, probably, was a way or a passageway of the phosphorus origin and hydrothermal action to increase the phosphorous inorganic-salt in seawater and to warm seawater. The phosphorous inorganic-salt and warmed seawater were beneficial to the origin and development of mulicellular organisms. In addition, the rich organisms also were helpful to the phosphate accumulation.
