摘　　要：芒花岭银金铅锌矿床产于华南褶皱系五指山褶皱带,昌江-琼海东西向深大断裂的构造-岩浆活动带上.研究区内岩浆活动强烈,有大量花岗斑岩岩株出露,长城系峨文岭组和下三叠统岭文组是这些岩体的直接围岩,矿体群呈带状沿NW向断裂带分布.矿石中主要的金属矿物为方铅矿、闪锌矿、黄铁矿、黄铜矿以及金矿物.根据物化探异常分析,圈出物探激电异常4处,化探异常3处.基于这些地质特征,对矿区进行了成矿预测.Manghualing silver-gold-lead-zinc polymetallic deposit is located in Changjiang- Qionghai E-W trending deep fault of tectonic - magmatic zone, Wuzhishan fold belt, South China fold system. The intensive regional magmatic activity can be confirmed by a lots of granite porphyry stocks intruded in Ewenling formation（Che） and Lingwen formation（ Tl l） in this study area, and the ore deposits are distributed along the NW trending faults. The main metallic minerals are galena, sphalerite, pyrite, chalcopyrite and gold-bearing minerals. According to the analysis of geophysical and geochemical anom- alies, four IP anomalies and three geochemical anomalies are circled. Based on these geological characteristics, the metal- logenic prediction of this area is given here.
