摘要
The common geochemical data usually show a normal distribution while the abnormal data exhibit a fractal distribution and local singularity. Three typical interpolation methods, IDW, Kriging and fractal, were discussed in this study. The conclusions are as follows: three methods have almost the same effect on the data with normal distribution; fractal interpolation is better than IDW and Kriging for the data with singularity. This study can help to choose interpolation method.
