自20世纪80年代以来,先后在俄罗斯、美国、加拿大、波兰等国发现并勘探了黑色高碳页岩型铂族元素矿床后,黑色岩系研究一直是国际学术界研究的一个热点话题。前人在黑色岩系方面的研究取得了许多重要的进展,包括黑色岩系的形成与缺氧事件有关、下寒武统黑色岩系可能是寒武纪全球变化事件的重要信息库、许多大型、超大型矿床的形成与黑色岩系密切相关。湘黔地区下寒武统Ni-Mo-PGE矿层是黑色岩系型矿床的典型代表,众多学者从不同角度研究了其物质来源和成因机制等 Since the 1980s, after the discovery and exploration of black high-carbon shale-type platinum group element deposits in Russia, the United States, Canada and Poland, the study of black rock series has been a hot topic in the international academic community. The predecessors’ research on black rock series has made many important progress, including the formation of black rock series related to anoxic events. The Lower Cambrian black rock series may be an important information base of the Cambrian global change events. Many large The formation of very large deposits is closely related to the black rock series. The Lower Cambrian Ni-Mo-PGE deposit in the Xiangqian area is a typical representative of the black shale deposits. Many scholars have studied their sources of materials and their genesis mechanisms from different perspectives
