构造地球化学法在大尹格庄金矿区Ⅰ号矿带的找矿应用

Application of tectonic geochemistry method to the prospecting in the ore zone Ⅰ of Dayingezhuang Gold District

  • 摘要: 大尹格庄金矿区Ⅰ号矿带的研究程度和勘探程度均相对偏低,通过构建大尹格庄金矿区构造地球化学异常成因模式,并对构造地球化学异常空间分布、套合性进行研究,结合多元统计分析与地质分析,认为Ⅰ号矿带深部寻找隐伏矿体的构造地球化学标志为Au-Ag-As-Sb-Bi组合异常;圈定找矿靶区6处,通过对A-1找矿靶区进行钻探工程验证,探获2层矿化,其赋存于含多金属硫化物的碎裂岩和黄铁绢英岩中。建议重视Ⅰ号矿带西部发育的大规模、高浓度和连续性好的Au构造地球化学异常,并对招平断裂主裂面下盘开展钻孔验证。

     

    Abstract: The ore zone Ⅰ of Dayingezhuang Gold District is explored and studied to a relatively low degree.Based on the genetic model of tectonic geochemistry anomaly,spatial distribution and register of tectonic geochemistry anomaly,multi-variable statistics,and geological analysis,Au-Ag-As-Sb-Bi integrated anomaly is determined as the tectonic geochemical evidence for prospecting concealed ore bodies deep in the ore zone Ⅰ;6 prospecting target areas were delineated.The A-1 prospecting target area was verified by drilling and 2 layers of mineralization were found,which occur in the cataclasite rich in polymetallic sulfide and the pyrite sericite.It is recommended that the prospecting pay attention to a tectonic geochemical anomaly of large scale,high concentration,and good continuity developed in the western part of the ore zone Ⅰ.In addition,drilling verification should be carried out in the footwall of the Zhaoping main fault zone.
