| 摘 要： | 黄地金-多金属矿床严格受黄地逆冲推覆断层控制,矿脉(体)赋存于由推覆体构造带上下盘岩石所形成的碎裂岩化、糜棱岩化带中,并且金、铅、锌在空间上具有分段富集的特点.矿石为动力变质多金属硫化物蚀变岩型,主要有自形-半自形、他形粒状,包含、碎裂等结构,块状、浸染状、角砾状等构造.金属矿物主要有黄铁矿、磁黄铁矿、方铅矿、闪锌矿以及银金矿和自然金,非金属矿物主要为石英和绢云母.自然金主要产于黄铁矿的晶洞中,少部分包裹于非金属矿物中.成矿作用可分为岩浆接触交代期、气-水热液矿化期和氧化期,其中气-水热液矿化期的早期石英-硫化物阶段为主成矿阶段,成矿物质主要来源于动力变质作用所形成的深部矿化热液,为沿推覆构造充填交代所形成.

| Abstract: | The Huangdi gold-polymetallic deposit is controlled by the thrust nappe faults of Huangdi strictly. The ore veins(bodies) are occurred in the cataclastic rock, mylonitization belts in the upper and lower wall of nappe structure. The gold,lead,zinc stepping enriches. The ore type is dynamic metamorphic polymetallic sulphide altered rock type, the texture concluding idiomorphic-hypidiomorphic granular, xenomorphic granular, poikilitic, cataclastic et al and massive,disseminated brecciform structure. The main metallic mineral are pyrite, pyrrhotine, galena,sphalerite and electrum and native gold, the main nonmetallic mineral are quartz and serictite. The native gold mainly occurred in the miarolite of pyrite,partly in the nonmetallic mineral. The mineralizing process can be classed as magma contact metasomatic period, gas-water hydrothermal mineralization period and oxidation period, among them, the early quartz-sulphide stage of gas-water hydrothermal mineralization period is the main ore-forming stage. The ore-forming metal from deep minerizating hydrothermal caused by dynamic metamorphism which along nappe structure filling and replacement. |
