摘　　要：皇华金铜矿位于胶莱盆地南缘,区内构造、岩浆活动强烈,发现多处矿点、矿化点,具有金多金属找矿前景。矿区内圈定了铜矿体、金铜矿体各1处,铜矿体长115m,真厚度2.46m,Cu平均品位0.837%;金铜矿体长124m,水平厚度2.70m,Cu平均品位0.42%,Au平均品位2.90×10^(-6)。矿(化)体位于地层与岩浆岩的接触地带,均赋存于郝戈庄断裂中,受构造控矿明显。矿床类型属构造蚀变岩型,构造蚀变带、碎裂岩化、孔雀石化、褐铁矿化、硅化等,均可作为找矿标志。Huanghua Gold-copper deposit is located in the southern margin of Jiaolai Basin,where tectonic and magmatic activities are strong.Many ore points and mineralization points have been found,which has gold polymetallic prospectingprospects.In the mining area,there is one copper body,one gold-copper body and one goldcopper body.The copper body length is 115m,the true thickness is 2.46m,and the average Cu grade is 0.837%.The gold-copper ore is 124m in length and 2.70m in horizontal thickness.The average grade of Cu is 0.42% and That of Au is 2.90×10^(-6).Mineralized bodies are located in the contact zone between strata and magmatic rocks,and all occur in Haogezhuang fault,which is obviously controlled by structure.The type of deposit belongs to tectonic alteration rock type,tectonic alteration zone,cataclastic,peacock fossilization,limonite,silicification and so on can be used as prospecting indicators.
