山东金亭岭金矿矿床地球化学异常分带模型

通过对山东金亭岭金矿各类微量元素和烃类组分在该矿床不同中段的含量变化以及在纵向上的异常展布和富集规律进行分析和总结,建立了该矿床的地球化学叠加异常分带理想模型,得出矿床地球化学异常轴向分带序列确定为:甲烷、乙烷、丙烷、正丁烷、异丁烷、乙烯、丙烯、Sb(前缘晕)→As、Hg(矿头晕)→Au、Ag、Pb、Zn、Cu、Mn(矿中晕)→Co、Ni、Mo、Bi(矿尾晕),并总结了找矿预测标志,为其深部找矿预测提供了一定的科学借鉴依据。

Geochemical anomaly zoning model for Jintingling gold deposit in Shandong province

Through a detailed analysis of the different content of all kinds of trace elements and hydrocarbon components in different mining levels in the Jintingling gold deposit,Shandong province,this paper has sum-marized the vertical anomaly distribution and enrichment regularities.The ideal geochemical anomaly zoning model has been established for this Au-deposit.The sequence of geochemical anomalies in the axial zone can be classified as follows.There are methane,ethane,propane,isobutane,n-butane,ethylene,propylene,Sb enrichment in geochemical front halo.There are As ,Hg,the middle halo is Au Ag,Pb,Zn Cu,Mn enrich-ment in geochemical head halo.The elements of Co,Ni,Mo,Bi are enriched within the trail halo as well. The article has proposed a basic summary of the prospecting signs for Jintingling gold deposit.It will provide the scientific basis for deep ore forecasting in the future.
