摘　　要：Early Cambrian black shales along the southern margin of the Yangtze Block are characterized by polymetallic mineralization in the lower part,including Ni-Mo sulfide ore,V ore,barite ore,phosphate ore,and"stone coal"(Fig.1a)[1,2],which were likely related to or at least coincident with the global ocean oxygenation event[3]and the radiation of early animals[4].The source of oreforming elements and the metallogenic mechanism of these polymetallic mineralization layers are highly debated.The models proposed include hydrothermal venting,seawater scavenging,and a combination of key mineralization factors such as terrigenous input,hydrothermal supply,seawater contribution,and impacts of clay mineral and organic matter(Fig.S1 online)[1].
