摘　　要：随着石竹山世界级硅灰石矿床的发现,赣西北蒙山岩体及其周缘成为近些年江西省找矿重点关注区,本文对蒙山岩体南侧东门铜多金属矿化点成矿地质特征和找矿潜力进行了分析。结果表明,研究区地球物理、地球化学异常较为明显,地表发育南北两处燕山期石英闪长斑岩,围绕岩体发育大规模矽卡岩化和大理岩化,伴随有铜、铁、钨、钼多金属矿化,具有找寻斑岩型和矽卡岩型铜多金属矿床的潜力。With the discovery of shizhushan world-class wollastonite deposit,Mengshan granite and its periphery have become the focus of ore prospecting in Jiangxi Province in recent years.This paper analyzes the metallogenic geological characteristics and prospecting potential of Dongmen copper polymetallic mineralization point in the south of Mengshan granite.The results show that the geophysical and geochemical anomalies in the study area are obvious.Yanshanian quartz diorite porphyry is developed in the north and south of the surface.Large scale skarnization and marble are developed around the rock mass,accompanied by copper,iron,tungsten and molybdenum polymetallic mineralization.It has the potential to find porphyry and skarn copper polymetallic deposits.
