摘 要:针对与义兴寨金矿找矿勘查密切相关的关键控矿因素,进行微量元素地球化学特征、同位素地球化学特征、含矿构造力学性质以及含金矿脉产出特征的对比分析。结果表明:燕山期中酸性岩浆侵入活动是矿床形成的主导因素,成矿在空间分布上与矿区南部超浅成相酸性岩关系最为密切;构造是成矿最重要的因素,控制了岩浆的侵入及其成矿岩体和矿体的形成和就位;地层则主要充当成矿期浅部领域内发育各种脆性控矿构造的良好围岩,以及在含矿流体的运移、聚集和定位过程中,充当良好的隔挡层。矿床成因属于典型的中低温岩浆热液型金矿床。In allusion to the key ore-controlling factors which is closely related to mineral exploration of Yixingzhai golden deposit, the geochemistry of trace elements, isotope geochemistry characteristic, mechanical property of ore bearing structure and the characteristic of gold-bearing veins output were analysed. The results show that the intermediate acid magmatic intrusive activities of the Yanshanian period are the dominant factor in the formation of deposit. The spatial distribution of mineralization is most closely related to the southern mining area with ultra-shallow phase acid rock. Structure is the most important factor in ore formation, which controls the intrusion of magma and the formation and perch of ore-beating rocks and ore body; stratum acts as favorable host rock of all kinds of ore control structures of the metallogenic epoch shallow place, and it acts as obstruct layer during migration accumulation and orientation of the ore-bearing fluid. The genesis of the ore deposit belongs to the typical magmatic hydrothermal gold ore deposit of the middle-low temperature.
