摘　　要：江西省修水县莲花芯铜钼多金属矿是近年来新发现的具有巨大潜力的矿床,主要的富矿围岩为中细粒黑云母花岗岩、中粒黑云母花岗岩和中粗粒黑云母花岗岩,主要的蚀变类型为硅化蚀变,矿石矿物类型主要为黄铜矿、黄铁矿和辉钼矿的组合,矿体主要受NW和NWW向的断裂构造控制,大量发育石英脉,矿化类型和矿石成因上与石英脉有着明显联系,矿化主要是见于石英脉内和石英脉两侧的围岩和硅化蚀变带中,矿化的强度向石英脉两侧不断减弱.化探取样结果显示该区有较高的W,Mo,Cu的异常.综合地质与化探的信息,划出三个找矿靶区,分别是W-Mo-Cu多金属矿靶区,W-Mo多金属矿靶区和W矿靶区.Lianhuaxin Cu-Mo polymetallic deposit in XiuShui county, Jiangxi province, is a recently discovered deposit with enormous potential. The metallogenic host rocks are mainly middle-fine grained biotite granite, middie-grained biotite granite and middle-coarse biotite granite, with silicated alteration as the major alteration type. Its ore minerals are mainly chalcopyrite, pyrite and molybdenum. And its ore body is mainly controlled by NW and NNW faults, which develops lots of quartz veins. The mineralization types and the ore genesis have obvious relations with the quartz veins. Mineralization is often seen in quartz veins, host rocks and silicated alteration zones on both sides of quartz veins, and the strength of which is weakened with the distance away from the quartz veins. The results of geochemical exploration samples shows high W,Mo,Cu anomaly, integrating the information of geological and chemical exploration, three prospecting target areas are delineated, they are W-Mo-Cu polymetal deposit target area, W-Mo polymetal deposit target area and W deposit target area, respectively.
