青山洞金矿床成因及找矿模型探讨

Discussion on genesis and prospecting model of Au deposit in Qingshandong

青山洞金矿位于湖南西南部的雪峰弧形构造成矿带上,是该成矿区带近年来新发现的重要金矿床。通过对青山洞金矿床地质特征的研究,分析其矿床成因类型属构造岩浆+变质热液并以充填交代方式形成的韧脆性剪切带型金矿床,具硫化物-自然金矿石建造,工业类型为破碎蚀变岩型。并初步总结了成矿模式并建立了找矿模型,为寻找同类型金矿提供参考和指导。

Qingshandong Au deposit locates at snowy peak arc structure metallogenic belt in north west Hunan, is an important Au deposit discovered recently. Through its geological characteristics research, data revealed Au deposit genetic type is tectonomagmatic province ＋ deterioration hydrothermal and filling and metasomatic type which has the sulfide-native gold ore formation, and the industrial type is fracture-altered rock-type. And summarized the prospecting model and has established the prospecting model, to seek for the same type Au deposit to provide the reference and the instruction.
