地球物理和地球化学异常的多重分形分析与分解

地球物理和地球化学异常是找矿的重要依据，异常的空间结构性包括奇异性和自相似性.奇异性反映了地球化学元素在岩石等介质中的局部富集和贫化规律，根据不同的自相似性特征可以分离地球物理和地球化学异常的背景场和异常场，有利于进一步评价异常与矿化的关系.近年来出现了基于空间域、付立叶域、特征值空间、沃尔什域的C-A、C-D、S-A、MSDV、W-A等异常的分解和分析方法，并成功应用于对地球物理和地球化学异常的解释中.本文对这些方法进行了概括和总结，探讨了小波域进行多重分形分析的方法在地球化学异常的分析和分解中的应用.并以山东乳山市葛口-石城测区的Au为例，以小波变换下的多重分形方法分析了该地区金成矿的可能前景，与实际情况较为吻合.

Geochemical and Geophysical anomaly separation and anomaly analyses based on multifractal

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 multifraetal 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 multifraetal 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-Shieheng region Rushang Shandong Province .
