摘要: 大尹格庄金矿床为一隐伏的(埋深距地表250m以上)中温热液破碎带蚀变岩型金矿床,现已经有十几年的开采历史,从目前验证钻孔剖面来看,矿体在深部有再富集的趋势。目前矿体控制最大斜深达890多米,矿体仍未尖灭,稳定向下延伸,显示矿床深部找矿的前景十分广阔。Abstract: The Dayingezhuang gold deposit in the Jiaodong area,Shan dong Province,is a hidden(to a burial depth of more than 250 m from the surface),mesothermal,alteration-type gold deposit in a fractured zone.It has been mined for more than ten years.Check drilling has revealed that the orebody has a tend ency of the second enrichment at depth.The orebody has a controlled maximum dip width of 890 m or more and still extends downward without pinching out,indicating that the deposit has very vast ore prospects at depth.
