黄铁矿型铜多金属矿床是与海底火山喷发—沉积建造有关的火山岩矿床 ,矿化赋存于一套微量元素总体含量水平较高的海相中酸性细碧角斑岩系中。赋矿地层、岩性具有以Cu ,Pb ,Zn为主 ,伴生Sb ,Ba,Ag ,As,Bi,Hg ,Cd等多元素的特征组合 ,这些元素在成矿区域上形成大范围的地球化学异常 ,其主体异常对应于矿田。矿区大比例尺的岩石地球化学测量显示 ,这些指示元素的清晰的原生异常相互交替叠置于矿床内矿化富集部位 ,水平分带不甚明显 ,而垂直分带清晰。具有不同指示意义的元素组合于矿化的不同部位聚集而出现的分带 ,是用于评价矿化剥蚀程度及其成矿远景的重要地球化学参量
Pyrite copper-polymetallic deposits are volcanic deposits related to submarine volcanic eruption-sedimentation. Mineralization takes place in a marine intermediate-acidic picisite-type porphyry with high total trace elements content. The ore-bearing strata and lithology have the feature combination of Cu, Pb, Zn and associated multi-elements such as Sb, Ba, Ag, As, Bi, Hg and Cd. These elements form a wide range of geochemistry Abnormal, its main anomaly corresponds to ore field. The large-scale lithogeochemical measurements of the mines show that the clear primary anomalies of these indicator elements are alternately superimposed on the mineralized enrichment sites in the orebodies. The horizontal zonation is not obvious but the vertical zonation is clear. The zonation of different assemblages with different indicator assemblages in different parts of mineralization is an important geochemical parameter for evaluating the extent of mineralization and its metallogenic potential
