| 中文摘要: |
| 矿区外围及深部的成矿预测需要对老矿区矿化空间分布进行定性分析,提取最有利的矿化指标,为控矿规律分析和成矿区圈定提供技术支持。文章以山东夏甸金矿床Ⅶ号矿体群为例,利用Surpac软件建立该矿区地质数据库,进行实验变异函数的计算与理论变异函数拟合,通过交叉验证,获取最优的搜索椭球体参数,构建搜索椭球体模型,揭示出矿体的矿化分布规律,最后在各三维坐标轴平面绘制矿化投影等值线图,直观地展示矿体内部金品位的连续方向,为矿化指标计算提供数据支撑。 |

| Qualitative analysis of spatial distribution of mineralization in old mining area and extraction of most favorable mineralization index is necessary for the ore prediction to the depth and in the surroundings. The analysis and extraction could provide technical support for analysis of mineralization law and delineate favorable metallogenic spaces of the predicted areas. This paper, taking ore body group Ⅶ in Xiadian gold deposit for example, builds geological database and uses Surpac software to calculate experimental Variograms and fit theoretical Variograms and obtain the best search ellipsoid parameters and build search ellipsoid model which reveals the distribution law of mineralization. Finally, the projection of mineralization contour map is drawn in the three-dimensional coordinate axis plane which intuitively display continuous direction of the gold grade inside ore body and provide a data basis for computing subsequent mineralization indicators. |
