分形滤波(S-A)技术在物探数据异常分解中的应用

分形滤波(S-A)技术能够有效地揭示地球物理场的空间相关性,对背景场以及异常场进行分解。应用分形滤波(S-A)技术分解内蒙古某银矿区地面高精度磁测异常,结果表明:对研究区高精度磁异常进行了有效分解,获得了研究区背景场以及异常场特征,并剖析所获得的异常场,分解异常8处,并据此结合地质情况提出研究区的成矿有利区。

Application of Fractal Filtering in Unusual Decomposition of Geophysical Data

Fractal filtering（S-A method） can reveal the spatial correlation of ge ophysical field and decompose the background field and anomaly field.Using frac tal filtering（S-A method） to extract the geophysical anomalies of a silver depos its in Inner Mongolia,the results show that fractal filtering technology can de compose the high-precision magnetic anomaly effectively.Based on the characteri stic of the background field and anomaly field in study area and analysis on the anomaly field,eight anomaly zones are extracted.Combining with the geological features,we give some suggestions on ore advantageous prospecting region in th e study area.
