Geochemical and Geophysical anomaly play an important role in mineral exploration,its spatial structure character includes singularity and self-similar.The singularity of an anomaly reflects the enrichment characters of the geochemical element,The anomaly separation by multifractal model is useful in mineral anomaly assessment.In recent years,C-A、C-D、 S-A、MSDV、W-A method to decompose the anomaly are presented.Those method are succeeded in interpretation of Geochemical and Geophysical anomaly.This study makes a summarization to these method,we discussed the multifractal method based on wavelet transform to analyze the geochemical and geophysical fields.It is demonstrated to be useful in interpretation of Au anomaly in Gekou-Shicheng region Rushang Shandong Province.
