Abstract: This paper briefly introduces the composition and the main technical parameters of the VTEMplus system, summarizes the technical advantages, describes the collecting data type and the method of data processing and the maps formed, with a brief descrip?tion of data interpretation methods. The measurement of massive sulfide mining areas in Hami of Xinjiang and Xiaoyingzias of Inner Mongolia shows the significant application effect of this method in polymetallic ore exploration, and hence this method deserves recom?mendation for future work. The results obtained by the authors have certain guiding significance for exploration of polymetallic and other mineral resources.
