摘要
红透山铜锌矿床赋存于辽北太古宙绿岩红透山岩组,为极具工业意义的大型矿床.通过对矿石H、O、S、Pb同位素特征的分析,结合矿床矿体形态、矿石结构、构造及围岩蚀变等宏观特征,认为红透山铜锌矿床成矿物质来源于太古宙晚期火山-沉积岩系,成矿流体来源于变质水和大气降水,成矿热力来源于变质作用,从而认为红透山铜锌矿床属"火山-沉积变质热液叠加"型层控矿床。
The Hongtoushan Cu-Zn deposit, located in the Hongtoushan rock formation of Archean greenstone in North Liaoning Province, is a large-scale ore deposit with great industrial significance. According to the analysis of H, O, S and Pb isotope characteristics, accompanying with the macroscopic natures, such as the orebody shape, ore texture, structure and wall-rock alteration, it is considered that the matter source of the Hongtoushan Cu-Zn deposit is the Neoarchean volcanic-sedimentary rock series. The ore-forming fluid is originated from atmospheric water and metamorphic water. The heat for ore-forming is from metamorphism. Thus the Hongtoushan Cu-Zn deposit belongs to stratabound type with volcanic-sedimentary and metamorphic hydrothermal overprinting.
