| 摘 要： | 文章根据勘探线地质剖面图钻孔样品化验数据和中段地质平面图坑道样品化验数据,利用Vulcan软件对大尹格庄金矿床矿体建立了两种三维实体模型,并将这两种模型结合起来,利用Datamine软件得到综合后的块体模型;运用地质统计学方法及Surpac软件,分析了①、②号两个矿（脉）体群的Au品位空间变化结构,并求得了搜索椭球体,实现了矿体和Au品位变化形态的空间分布展示;结合三维建模成果与矿体空间变化结构,分析得出了矿化分布规律.②号矿（脉）体群沿NE向继续展布的区域,是寻找深部隐伏矿体的有利部位.

| Abstract: | Based on analysis of core samples on section of the exploration line and samples of tunnels on the geological plan of levels software Vulcan was applied to build two types of 3-D solid models for ore bodies in the Au deposit and the software Datamine-based block model built by combination of the models. The spatial Au grade variation of ore body group （1） and （2） are analyzed by geostatistic method and software Surpac and a search ellipsoid obtained and variation morphology of Au grade and spatial distribution of ore bodies shown. Combined with results of the 3-D modeling and Au grade variation structure the mineralization pattern is given. Further prospecting of deep blind ore bodies should be conducted in both directions of NE extension of the ore body group （1） and （2）. |
