摘　　要：东乡南部地区位于钦杭结合带江西段中东部,发生过多次构造-岩浆-(沉积)变质-成矿事件。区内岩浆活动强烈,以为加里东期和燕山早起岩浆活动为主,次火山岩分布广泛,且含矿性较好;区内断裂及火山构造发育,是岩浆运移的重要通道、导矿、容矿构造,控制矿体分布;区内地层为白垩纪火山岩,矿化与火山岩成矿元素含量密切相关。本文根据成矿地质条件,分析矿区找矿潜力,指导区内金多金属矿床勘查工作。The southern part of Dongxiang is located in the Middle East of the Jiangxi Section of the qinhang junction zone,where there have been many tectono magmatic-(sedimentary)metamorphism mineralization events.The magmatic activity in the area is strong,mainly in Caledonian and early Yanshanian magmatic activities,and the subvolcanic rocks are widely distributed with good ore-bearing property;the faults and volcanic structures in the area are developed,which are important channels for magma migration,ore guiding and hosting structures,and control the distribution of ore bodies;the strata in the area are Cretaceous volcanic rocks,and mineralization is closely related to the content of ore-forming elements of volcanic rocks.According to the metallogenic geological conditions,this paper analyzes the prospecting potential of the mining area and guides the exploration of gold polymetallic deposits in the area.
