黑色岩系,作为众多多金属矿床的矿源层,具有重大的经济和科研价值而广受国内外学者关注。中国南方下寒武统黑色岩系中广泛产出大中型金属型矿床,如Ni-Mo矿、V矿及PGE矿。但同时作为能源矿产的页岩气在下寒武统黑色岩系中也广泛成藏,因此有必要研究两者之间的耦合关系。本文综述前人已经发表的黑色岩系的一些地球化学特征,特别是有机地球化学特征,初步揭示金属成矿与页岩气成藏之间的耦合关系,研究成果有利于进一步探讨黑色岩系型金属成矿与页岩气成藏的沉积古环境,对指导金属矿床与页岩气藏资源协同勘探及综合预测及开发具有重大科学意义。
Black rock series, as the source layer of many polymetallic deposits, has great economic and scientific value and is widely concerned by domestic and foreign scholars. Large and medium-sized metallogenic deposits such as Ni-Mo, V and PGE are widely produced in the Lower Cambrian black rock series in southern China. However, at the same time, shale gas, as an energy mineral, is also extensively accumulated in the Lower Cambrian black rock series. Therefore, it is necessary to study the coupling relationship between the two. This paper reviews some of the geochemical features, especially the organic geochemical features, of previously published black rock series, and initially reveals the coupling relationship between metallogenetic mineralization and shale gas accumulation. The research results are helpful to further explore the black rock series The metallogenetic and sedimentary paleoenvironment of shale gas accumulation has great scientific significance in guiding the collaborative exploration, comprehensive prediction and exploitation of metallogenic deposits and shale gas resources.
