| 摘 要： | 在新疆恰尔隆一带水系沉积物地球化学找矿中,应用Excel电子表格采用＂迭代剔除高值法＂计算背景值和标准偏差,进而求得异常下限,并根据此异常下限,再利用MapGIS软件绘制出单元素异常图及综合异常图。实践证明,通过MapGIS与Excel的应用提高了工作效率,为地质找矿快速直观地提供了找矿信息。

| Abstract: | In the process of stream sediments geochemical prospecting in Qia-erlong area of Xinjiang,we calculate the background value and Standard deviation by the means of "Iterative eliminate high value method" in Excel electronic form,and then get anomaly thresholds.According to these anomaly thresholds,we map out the single element anomaly maps and the anomaly comprehensive maps by MapGIS software.The experimental result shows that the application of MapGIS and Excel improves the working efficiency greatly,which plays an important role in providing quick and direct information for geological prospecting. |
