| 摘 要： | 西秦岭礼岷成矿带具有良好的成矿地质条件,找矿潜力巨大。通过对该区域4个金矿床硫同位素、碳氧同位素、氢氧同位素、微量元素、稀土元素及流体包裹体对比,发现礼岷地区金矿床成矿物质主要来源于晚古生代沉积岩(主要为李坝群),成矿流体以大气降水为主,早期有部分岩浆水和变质水参与成矿。认为成矿于中低温弱矿化度、弱酸性、弱还原条件下。目前除中川岩体外,其他岩体周围也具备同样的成矿条件,本文旨在其他岩体周围取得金矿勘查的新成果提供借鉴。

| Abstract: | LiXian-Minxian metallogenic belt of Western-Qinling have good mineral-forming have good mingeral-forming condition and great prospection potenital.The comparative analysis results of four Gold Deposits's aurum and it's associated elements,isotope elements(sulfure,oxygen,carbon and hydrogen),trace elements,REE and the fluid inclusions indicate that the ore-forming materials maily come from the Upper Paleozoic sedimentary rock(most from Liba Group),and the mineralizing fluids water is mainly rainwater,less ma... |
