摘    要：甘肃大水金矿床是西秦岭地区的一个特大型金矿床,也是一个国内外十分罕见的新类型金矿床。随着矿山向深部开采,品位急剧下降。选择其77勘探线5个开采中段系统地采集了岩石样品,在进行统计分析、R型聚类分析、因子分析的基础上,确定了大水金矿床地球化学原生晕轴向分带序列,建立了该金矿床轴向分带的原生叠加晕模型,并对深部含矿性作了初步评价。

Abstract: Dashui gold deposit in Gansu province was not only a super large gold deposit of west Qinling region,but also a new type gold deposit which was extremely rare at home and abroad.Rock samples were systematically collected in 5 middle sections of No.77 exploration line.On the basis of statistical analysis,R-type cluster analysis and factor analysis,the axial zoning sequence of the geochemical primary halos of Dashui gold deposit had been defined.The primary superimposed halo model of the axial zoning sequence of this gold deposit was established.Then the preliminary assessment on deep mineralization potentiality was made.
