摘　　要：云南广南斗月—羊街金矿区位于云南省东南部,处于我国滇黔桂贵金属成矿带上。金矿床主要受岩性及小型断裂构造控制。富矿岩石主要为二叠系玄武岩、凝灰岩及沉凝灰岩。富矿岩石均褐铁矿化且90%以上发育有石英细脉。文章旨在从岩石的岩相学特征及微量元素特征着手,初步推测该金矿区的矿床成因,并预测其成矿前景。Douyue-Yangjie gold mine in Guangnan,Yunnan is located in the southeast of Yunnan Province,which is in the Yunnan-Guizhou-Guangxi precious metal metallogenic belt in China.The gold mineral deposit is mainly controlled by lithology and small fracturing structure.The mineral-rich rocks are mainly Permian basalt,tuff and sedimentary tuff.The mineralrich rocks are all limonitized and more than 90%of them are developed with quartz veinlet.The purpose of this paper is to preliminarily speculate the genesis of the gold mineral deposit and predict its metallogenic prospect from the petrographic characteristics and trace element characteristics of rocks.
