【摘要】 焦家金矿床具中温、中深成特点,其主要成矿温度为250～320℃,压力800×10-5Pa,fo2=10-34～10-36。S、C、Pb同位素分布集中,反映了成矿环境较稳定;成矿金来源以胶东群含金建造为主、深部物质来源为辅。成矿热液中的水以大气降水为主,岩浆及变质水也有少量加入,反映了成矿的长期性和继承性,同时也说明区域性的深大断裂—焦家断裂对金的成矿控制作用明显。更多还原

【Abstract】 Jiaojia gold deposit is controlled by region fault and alternation zone, the producing temperature ranges mainly from 250℃ to 320℃, the pressure is 800×105Pa,fo2=10-34～10-36, the concentration of sulphur, carbon and lead isotopes reflect the stability of geological settings.The gold element is mostly derived from Jiaodong group, secondly from the depth, hydrothermal is mainly come from meteoric water and magnetic water, transformation water, reflecting the long and inherit oreformation.更多还原
