摘　　要：广东乳源一六钨矿区位于早期东西向基底构造与晚期新华夏系褶断带的复合部位,北西和北北东两组断裂为主要控岩控矿构造.矿区发育两期岩浆活动:燕山早期形成的宝山岩体受东西向基底构造的控制,燕山晚期的一六岩脉沿断裂侵入.矿区内的蚀变类型主要有矽卡岩化、云英岩化、硅化和碳酸盐化4种.矿区主要有矽卡岩型和云英岩化石英脉型两种类型的白钨矿化.地层、构造、岩浆岩共同控制白钨矿矿化,组成了构造-蚀变-矿化网络.文章通过对矿区构造-蚀变特征及其与矿化关系的研究,初步建立了一六钨矿的构造-蚀变-矿化网络模式.The Yiliu tungsten area in Ruyuan of Guangdong is located in the combining site of east-west base structure and Neocathaysian fold-and-thrust belt, in which the dominant rock and ore-controlling structures are the NW-striking and NNE- striking faults. Two periods of magmatic activities developed in the district are the early Yanshanian Baoshan roekbody con- trolled by east-west base structure, and the late Yanshanian Yiliu dike intruded along the faults. The alteration types in the mining area are mainly skarnization, greisenization, silicification, and carbonatization. There are mainly two types of min- eralizations in the area, which are skaru-type one and greisenization quartz vein type one respectively, and were controlled jointly by strata, structures, and magmatism, comprising the structure-alteration-mineralization net. Based on structure-al- teration characteristics and its relation to the mineralization, a structure-alteration-mineralization network pattern of the Yi- liu tungsten deposit is established.
