摘要
A detailed trace element study of chert from the Laobao formation,which is a terminal ediacaran （551～542 Ma） succession in South China deposited in deep-water basinal setting, was reported in this paper. The new geochemical results in this text reveal that the deep-water of the terminal ediacaran in South China Basin was ferruginous, and could create necessary conditions for the emergence and rapid evolution of multicellular metazoans.
