摘　　要：双频激电法在西藏高海拔地区多金属矿调查中的应用,是在充分研究远景区的地质条件、地球物理特征的前提下,选用双频激电的中梯装置以及对称四极测深装置对重点区进行探测,结果表明多个区的多金属矿激电异常非常明显。根据视幅频率异常等值线平面图及激电测深拟断面图,准确地圈定了矿化区域和矿化体产状特征,以其中一个重点的探测结果为例进行了详细说明。This paper discusses the application of dual--frequency IP method in several polymetallic ore deposits in the high altitudes areas of Tibet of China. Based on the integra- tion analysis of the geological and geophysical information, we used the middle--gradient and symmetric quadrupole sounding of dual--frequency IP method in the core area. And the result shows IP abnormity in some polymetallic ore deposits is obvious. We confirmed the mineralization zone and the mineralization body occurrence characteristics according to the apparent frequency amplitude anomaly contour map and pseudo section map. This paper gives a detailed description by taking one main prospecting area as an example.
