摘要
随着地表金矿资源的开采与枯竭,深部勘探成为未来金矿勘查的必然选择,因此深部找矿预测研究也是势在必行.金宏金矿床成矿严格受构造控制,矿床类型为石英脉型,本文结合金宏金矿矿区地质背景、矿体地质特征、坑道及钻孔岩石地球化学特征分析,系统研究了矿区V8号金矿体原生晕地球化学特征.研究表明,金宏金矿床As、Ag、Hg与Au成矿关系最密切,Sn与金成矿关系不密切;与典型金矿床原生晕垂直分带序列对比分析,金宏金矿床具有原生叠加晕特征,是多期次成矿成晕的结果;并根据原始晕垂直分带序列特征对金宏金矿床开展了深部找矿预测.
Abstract
With the exploitation and depletion of surface gold resources,deep exploration becomes the inevitable choice of future gold exploration,so deep prospecting prediction research is also imperative.The mineralization of Jinhong gold deposit is strictly controlled by structure and the deposit type is quartz vein type.Based on the analysis of geological background,geological characteristics of ore body,and geochemical characteristics of rock in tunnel and borehole of Jinhong gold deposit,the geochemical characteristics of primary halo of No.V8 gold ore body in Jinhong Gold deposit are systematically studied.The results show that As,Ag and Hg are most closely related to Au mineralization in Jinhong gold deposit,while Sn is not closely related to Au mineralization.Comparing with the vertical zonation sequence of primary halos of typical gold deposits,Jinhong gold deposit has the characteristics of primary superimposed halos,which is the result of multi-stage metallogenic halos.The deep prospecting prediction of Jinhong gold deposit is carried out according to the characteristics of the original vertical zoning sequence of halo.
