Abstract In order to investigate the geophysical parameters of the important ore concentration areas in Anhui Province, the authors studied the anisotropy of rock electric parameters. Selecting sedimentary and metamorphic rocks in Huoqiu ore concentration area, Lujiang-Zongyang ore concentration area, Ningwu ore concentration area and Dongzhi-Jingxian metallogenic belt as study samples, the authors tested the three directions of the resistivity and polarization. The result confirms that the anisotropy of rock resistivity is extremely obvious. It is found that the higher the resistivity, the higher the ratio of the vertical resistivity to the horizontal resistivity. The anisotropy of rock polarization also exists, but it is not obvious. The anisotropy of resistivity exists in sedimentary rock, metamorphic rock and volcanic sedimentary rock. Based on data analysis of rock anisotropic electrical parameters, the authors summarized the anisotropy characteristics of rock electrical parameters, which provides basic data and foundation for the study of geology, the comprehensive understanding of the previous data and the comprehensive interpretation of electrical prospecting.
