摘要
山东省莒南县东书院金矿是胶南隆起上曾开采过的小型金矿床,金矿石类型为黄铁绢英岩化碎裂岩型,矿床工业类型为中低温热液岩浆型矿床。采用激电中梯测量与钻探资料结合,共圈定金矿体3个。其中,AuⅠ矿体为矿区主体,金品位(2.64~4.28)×10^(-6),平均品位3.46×10^(-6)。
Dongshuyuan gold deposit in Junan county of Shandong province is a small-sized deposit with industrial value in Jiaonan uplift. The gold ore type was beresitization cataclastic rock,and commercial type of mineral deposit was medium-low temperature hydrothermal magmatic deposit. By using induced polarization gradien array measurement,combining with drilling data,three gold ore bodies have been circled. Among them,the AuⅠ ore body is the main body in the mining area. Its gold grade is（ 2.64 - 4.28） ×10^-6,and average grade is 3.46×10^-6.
