| 摘 要： | 本文研究如何用地质统计学方法处理服从对数正态分布的化探数据的问题。经对湖北阳新岩体铜含量数据的大量电算、分析、对比,最后选用了对数泛克立金法。由计算机自动绘出的估值图和漂移、剩余图能很好地反映该区化探趋势和异常,既优于趋势面分析和滑动平均法,也优于泛克立金法,且能获得较稳健的变差图。故此法对化探数据自动成图很有用处。

| Abstract: | This paper studies how to use the geostatistical method in processing geochemical data, which follows the lognormal distribution. After comparing the calculated results of universal kriging and logarithmic universal kriging, it shows that a more satisfactory result is drawn from the application of logarithmic universal kriging in geochemical data processing. In other words, using this method, we can make a contour map of geochemical anomaly, which is rather in accordance with the field geologic phenomenon. So this method is very useful for the computer automatic contouring of geochemical data. In this papar the robustness of variogram of the geochemical data has also been studied. |
