摘　　要：根据大井西部矿区ZK-29-3、ZK-49-2钻孔中发现的闪长岩体及其岩石学特征,以及对钻孔岩石地球化学特征的分析,论述大井锡多金属矿床深部发现闪长岩体的找矿意义。初步认为,矿区深部存在第二矿化空间和新的矿化类型,具有斑岩系列钼(金)多金属矿的找矿潜力。The significance of the discovery of diarite in depth of the Dajing deposit was discussed according to the diarite rock discovered in ZK-29-3,ZK-49-2 bore hole in western ore field of Dajing and its lithology as well as the analysis on the bore hole rock geochemical characteristics. It is believed that there is a second mineralization location and new mineralization type in the depth of the mine with molybdenum （gold） polymetallic ore potential of porphyry series.
