Abstract:The skarn type polymetallic deposit is controlled by contact zone, the fault and the interlayer fracture zone. It occurred in the skarn in the contact zone. The target body and the surrounding rock are different in terms of magnetic and electrical properties. By using appropriate geophysical methods, the strike of the ore body has been tracked, and spatial occurrence state of the ore bodies has been understood. It will provide a basis for the disclosure of the deep. Highprecision magnetic measurement and the induced polarization method can quickly delineate the projection position in the surface of target body caused by magnetic anomaly. By using quadrupole sounding method, spacial occurrence state of polar body can be understood. By using different pole distance composite profiling method, the tendency of the polarized body can be determined. It has good application effect to find skarn type polymetallic ores in HaDer Gannan area and Altek mountain area in Qinghai province by means of comprehensive geophysical method. It will play an important role in searching skarn mineralization zone.
