| 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。

| Abstract: | 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. |
