摘要
对陕西宁强县大茅坪铜矿床铜矿石品位统计特征进行了研究 ,初步认定该矿床铜矿石是两期成矿作用的结果 ,铜元素的总体分布属混合分布类型。用混合总体筛分法和因子分析法 ,基本可定量确定各期的矿化范围、强度以及与铜矿化作用相关的元素组合 ,指出寻找此类矿床的地化找矿标志。
By studying on the statistics of ore grade of Damaoping copper deposit in Ningqiang,Shaaxi province,it is initially identified that this deposit is the product of two stages mineralization Cu distribution belongs to mixed type in totally After using mixed total sizing analysis and factor analysis methods,mineralization area of various stages,mineralization strength and elements assemblages related to Cu mineralization are determined quantitatively,and it is put forward that ore finding indicators of geochemistry
