| 摘 要： | 以新疆阿舍勒地区铜矿GIS预测为实例，说明线型异常和面型异常的找矿有利度分析方法，并给出断裂、有利地层和物化探异常找矿有利度分析的结果。给出计算空间相关性的公式，并研究了不同元素化探异常的空间相关性。最后，研究了不同元素的组合异常，论证了在矿产预测中应用组合异常的必要性并利用GIS进行了找矿有利地段的圈定。

| Abstract: | Analysis method of ore - finding beneficial degree in linear and plane anomalies is explained with the example of copper deposit prediction in the Ashele area, Xinjiang. Ore - finding beneficial degree of fault, geochemical - geophysical anomaly and stratum is proposed. Spatial correlation of geophysical - geochemical anomaly of different elements is studied by the spatial correlation formula. Element assemblage anomaly is also studied, and necessity of assemblage anomaly in mineral deposit prediction is demonstrated. |

| Keywords: | mineral deposit prediction GIS ore- finding beneficial degree spatial correlation |
