摘　　要：胶南七宝山位于胶东半岛东部地区,区域上属于胶南—威海造山带。山东省地质调查院在此开展普查工作,并通过激电测深、土壤测量、钻孔取芯,以及化学和光谱等分析方法,得出铅矿矿体赋存于断裂构造中,属岩浆热液充填型。矿体主要呈脉状、凸镜状,宽1～3m,长70～200m,主要矿体走向近南北,多倾向东。矿石有用化学成分主要为Pb、Ag、CaF2、Cu,Pb含量一般为1.36%～3.96%(平均3.11%),矿体平均厚度3.13m。Qibaoshan Pb deposit is located in the eastern Shandong Peninsula, and lain in the Jiaonan -Weihai orogenic belt. Shandong Institute of Geological Survey has done reconnaissance works in the area. Lead ores are distributed in fractures, and belongs to magatie hydrothermal filling type. The ore bodies exist as veins and lens with 1 -3m width and 70 -200m length. Trend of the main ores, dipping to east, is near south - north. Useful chemical compositions are Pb, Ag, CaF2 and Cu. Pb content is 1.36% - 3.96% with average of 3.11%. The average of thickness of ore bodies is about 3.14m.
