摘要: 河南省文峪金矿通过信息综合趋势分析认为在水平方向上505矿脉是成矿元素地球化学场的中心带，向两侧减弱.随着深度的增加，地球化学场中心带开始向北（530脉）转移.垂直方向上，530脉，从现在生产标高向深部，Au品位和矿体厚度将呈下降趋势，但在深部相对富矿段预测为x=46.20~46.40范围.分析结论被后来生产勘探所证实，并获得大量的工业储量，表明该方法是可行的Abstract: Wenyu gold deposit of Henan Province,located in the center of Xiaoqinling gold field,is quartz vein type hosted in Archean Taihua group,including more than 80 ore veins The trend analysis of comprehensive information suggests that Vein No.505 is horizontally the central zone of elementray geochemical field The central zone deviates northward(to Vein No.530)with the increasing depth Vertically,the Au grade and the thickness of orebody of Vein No.530 tend to decrease from the mining level to the deep But a relatively rich section is predicted at x=46.20~46.40 The result has been confirmed by mining exploration,and more reserves has been obtained,showing that the method is a practical one
