Abstract: Following with the development of mineral exploration practices and the difficulties in prospect forores, mine area large -scale ore body fast locating prediction has became an important research topic in the domain of mineral exploration. The advan tages of VLF-EM method are portable, simple, economic and efficient. As a superficial-layer geophysical prospecting technology, its effect is good through practical check of mineral exploration in China and abroad. This paper briefly discusses the basic principle of VLF method and its data processing technology. On the basis of deposit geology research, this article establishes ageology-geophysics fast loca lization prediction model of the target ore body by using the verylow frequency elect romagnetic (VLF-EM) technology in Fengning Menying CU polymetallic deposit; practice shows that, utilizing this method to collectlarge-scale geophysical data and combined with studies of Fraser filtering and linear filtering. This method can be successfully applied to determine spatial occurrence and extension of buriedore bodies and can provideopt imaltarget area for the employment of exploration engineering. It is worth to pointout that, because of the in terference of geology noise and environment electromagnetic noise, geological characteristic analysis and comparative study of in terp retation results and their 2D、3D expression is the critical factor to extract ore induced anomaly.
