Tongshi is located in the west of Yishu fault western Shandong uplift area,also it is a newly discovered gold-bearing concentrated area last century.Yanshan period’ Tongshi igneous complex intrusive and control the distribution of gold deposits.According to the previous experience of deposit exploration,and combining with the similar conditions adjacent areas’ prospecting experience inferred that Tongshi the forming limit depth of gold is under the bottom of Cambrian Changqing Group Zhushadong Group Dingjiazhuang dolomite paragraph.That is between Cambrian sedimentary cover with Precambrian crystalline basement unconformity.Above the unconformity surface is a favorable location for gold mineralization.According to the thickness of true formation and combining with stratigraphic occurrence.Calculating out of the ground to a vertical distance of unconformity is corresponding metallogenic gold prospecting target ore bodies buried depth.Estimating the depth of mineralization to provide a basis for deep drilling engineering design.
