摘　　要：陕西双王金矿是国内著名的金矿床,以其中Ⅳ号角砾岩体内的矿化最好.本文通过对Ⅳ号角砾岩体内的KT7,KT8,KT9这3个矿体的品位、厚度、线金属量、矿化指数等参数在空间上变化特征的研究,揭示了Ⅳ号角砾岩体的矿化规律.研究结果表明,沿矿体SSE走向方向3个矿体矿化变好、矿化强度增强且矿化富集中心呈雁列状分布;KT9与KT8矿化形式相似,但不及KT8矿化好;随标高降低,垂直矿化指数具有隔50 m强弱交替变化的特征;矿体品位与厚度的相关性受矿化水平影响,当矿化一般时,二者为正相关,矿化变好时,二者不相关,矿化变得更好时,二者为负相关.The Shuangwang Gold is a leading gold deposits in China,the No. Ⅳ breccia of it mineralized best. By researching the parameters of KT7,KT9,KT8 ores of No. Ⅳ breccia,such as grade,thickness,line metal content,mineralization,varing in space,this paper reveals the No. Ⅳ breccia's mineralization regularity.The results of the study show that ore mineralizes better, mineralization intensity increases and enriched mineralization center was echelon like distribution,along the ore body SSE strike direction. KT9 has the similar form mineralization with KT8,but not as good as KT8 mineralization. With lower elevation,vertical mineralized index has the characteristics of strength alternating every 50 m. Ore grade and thickness correlated with the level of influence by mineralization,when mineralization general,the positive correlation between the two mineralized changed for the better when they are not related to mineralization are better off,both negative related.
