以胶东半岛乳山寨幅1∶5万水系沉积物测量为例,利用化探数据进行因子分区讨论,得到7个地球化学分区,分别为:Au、As、W地球化学分区,Pb、Ag、Zn地球化学分区,Bi、Sb地球化学分区,Ni、Cu地球化学分区,Sn地球化学分区,Mo地球化学分区,Hg地球化学分区.结合圈定的金综合异常,在Au、As、W地球化学分区内,发现金矿化点2处.结果表明,分区与化探成矿信息的对应关系较好,可以达到缩小找矿靶区,指导找矿工作方向的目的.
Application of Geochemical Zoning Method in Geochemical Exploration——Taking the Measurement of Water System Sediments with the Scale of 1∶50000 in Rushanzhai in Jiaodong Peninsula as an Example
Taking the drainage sediment survey with the scale of 1∶50000 in Ruzhai area in Jiaodong Penin-sula as an example,by using geochemical exploration data,the factor zoning has been discussed.7 geo-chemical zones have been obtained,they are Au,As,W geochemical zoning;Pb,Ag,Zn geochemical zoning;Bi,Sb geochemical zoning;Ni,Cu geochemical zoning;Sn geochemical zoning;Mo geochemical zoning;Hg geochemical zoning.Combining with the delineated gold synthetical anomaly,two gold miner-alization spots have been found in Au,As,W geochemical zone.It is showed that the corresponding rela-tionship between the zoning and geochemical and metallogenic information is good.It can achieve the pur-pose of reducing the prospecting target area and guiding the prospecting direction.
