中文摘要:
      为了突破长白山玄武岩覆盖区寻找隐伏矿难题,选择长白山果松村试验测区开展地电化学找矿研究。通过地电提取对各元素进行多元统计分析,其中具有代表性的元素组合为As-Mo-Bi-Co-Ni-Cr、Cu-Pb-Zn、Ag-Sb和Au-Hg。元素组合异常分布规律:从外围至内带依次为Ag-Sb、Au-Hg、Cu-Pb-Zn、As-Mo-Bi-Co-Ni-Cr组合。其中,代表矿体前缘晕的Ag-Sb、Au-Hg元素组合异常主要分布在隐伏矿体外围,可作为追索隐伏矿体的依据;Cu-Pb-Zn和As-Mo-Bi-Co-Ni-Cr分布在内带,可作为与Cu、Pb、Zn、Co、Ni、Cr等成矿元素相关矿种的直接找矿标志,其异常浓集中心指示隐伏矿体位置。总体而言,地电化学在长白山玄武岩覆盖区找矿效果良好,值得推广运用。
英文摘要:
      In order to solve the problem of prospecting concealed deposit in basalt coverage area in Changbai mountain, Jilin, the geo-electrochemical method was selected for the application in the Guosong village test area. Based on multivariate statistical analysis result of the elements collected by geo-electrochemical extraction approach, the typical combination of elements as followings:As-Mo-Bi-Co-Ni-Cr, Cu-Pb-Zn, Ag-Sb and Au-Hg. The distribution regulation of element combination anomaly from the periphery zone to the inner zone is as followings:Ag-Sb, Au-Hg, Cu-Pb-Zn, and As-Mo-Bi-Co-Ni-Cr. Among them, the Ag-Sb and Au-Hg element combination anomalies were mainly distributed in the periphery of the concealed ore body, therefore, they can be used as the basis for the tracing of concealed ore bodies. The Cu-Pb-Zn and As-Mo-Bi-Co-Ni-Cr element combination anomalies in the inner zone can be used as prospecting mark for concealed ore bodies of Cu, Pb, Zn, Co, Ni, Cr and other ore-forming elements, the abnormal concentration center commonly represents the position of concealed orebodies. As a whole, geo-electrochemical method is an effective prospecting approach in basalt coverage area, therefore it is worth of wide application.
