摘要
蛇屋山金矿产于以寒武－奥陶系碳酸盐岩为主体的倒转背斜及双重逆冲构造中；矿床属低温热液成因（原生金矿）；浅部矿体，即缓倾斜断层构造岩中的原生金矿，经历了第三纪以来近亿年的风化淋滤改造，成为可露采、易堆浸的风化金矿床；矿石品位低，金呈微细粒浸染状。与美国卡林型金矿类比，该矿属卡林型金矿。蛇屋山卡林型金矿分为原生金矿和风化金矿两个亚类。
Shewushan gold deposit occured in overtured anticline and double thrust tectonic whichwere mainly composed of Cambrian-Ordovician Carbonatite，and belong to epithermal oredeposit（primary gold deposit）．The Shallow orebody，that is primary gold deposit occuredin gently dipping fault tectonite underwent near a hundred million years' weathering-Leach-ing transformation，and became strippable weathering gold deposit．Ore grade is low. Gold ap-peared in micro-fine grained impregnation state. Compared with Carlin type gold deposit，Shewushan goid deposit belong to Carlin type and can be divided into two subtypes：primaryand weathering gold deposit.
