摘　　要：通过分析金驹山矿区的地层、构造、岩浆岩、围岩蚀变及矿石构造等地质因素,认为金驹山矿区的断裂构造严格控制着矿区内矿脉和岩脉的规模、产状及产出位置,是矿区的主控矿因素,同时也是矿区的主要找矿标志;粗安斑岩与矿区成矿热液源于同一母岩浆,其分布对矿体分布有一定的指示意义。同时总结矿区成矿规律,认为金驹山矿区神墩山与金驹山之间第四系覆盖区和矿区以北曲山地区为今后寻找金驹山类型矿床的有利地段。Through analyses of geological factors like stratigraphy, structures, magmatic rocks, wall rock alteration and ore structures in Jinjushan ore district, the authors considered that the fault structures were the main ore-control factors and primary ore exploration indicators, they strictly controlled the scale of veins and dykes, occurrences and outcrop positions in the ore district. The study showed that the trachyandesite-porphyry and the mineralizing fluid were from the same magmatic source, which indicated the position of the veins to a certain extent.
