摘　　要：大山排矿区位于南岭W-Sn-Mo-Be-REE-Pb-Zn-Au成矿带之北东缘的银坑矿田内,区内矿化分布普遍,成矿条件优越。在大山排矿区详查地质工作的基础上,对矿区铅锌金银矿地质特征、矿床特征等进行了归纳总结,认为主要成矿元素应为Pb、Zn、Au、Ag,具矿化面积大、强度高、受断裂构造控制明显、与岩浆活动有明显联系之特点,属岩浆活动有关的热液矿化;矿床成因类型属中低温充填-交代型铅锌银金铜多金属矿床。Dashanpai deposit is located in Yinkeng ore field which belongs to Nanling W-Sn-Mo-Be-REE-Pb-Zn-Au metallogenetic belt.It has widespread mineralizations and superior metallogenetic conditions.Through the detailed survey,the geological characteristics and deposit characteristics of the deposit has been concluded.Its primary metallogenetic elements should be Pb、Zn、Au、Ag,it also has wide mineralization area and high mineralization intensity.It is significantly controlled by the fault structure and highly related to magmatic activity,it is hydrothermal mineralization which is related to magmatic activity.The genetic type of the deposit is medium-low temperature replacement and filling lead-zinc-gold-silver polymetallic deposit.

关 键 词：多金属矿床 热液矿化 大山排矿区 银坑矿田
