Electrical resistivity anisotropy of rocks has significant influence on measurements and interpretation of electrical and electromagnetic data. Hence, the estimation of anisotropy can provide additional and accurate information about the subsurface. Its negligence during the inversion can lead to erroneous results. Capabilities of the near surface controlled source radio magnetotelluric (CSRMT) method, which utilizes a horizontal electric dipole (finite length cable) for the estimation of electrical resistivity anisotropy of a horizontally layered subsurface from measurements in the transition zone of the source, are thoroughly discussed in this article. Synthetic modelling studies helped us to determine the parameters for field measurements such as a survey area position near the transmitting cable, its length, transmitter-receiver orientation etc. In addition, a comparison of the synthetic results and the field data, measured over a simple vertically anisotropic 1D geoelectrical section, is done. This exercise facilitates to explain the cause of different sensitivity to the vertical resistivity for different transmitter lengths and Tx-Rx orientation. Synthetic integral sensitivity of impedance for the vertical resistivity of the anisotropic layers is calculated and plotted, which deciphers the area of the maximum sensitivity to the vertical resistivity. This emphasizes that the CSRMT data measured in the transition zone of the cable are affected by the significant impact of both galvanic and inductive modes, which helps in the estimation of macro-scale anisotropy. These data can be used for the purpose of industrial construction, particularly in the selection of appropriate repositories to keep the isolation of the solidified radioactive waste in the Cambrian clays of the North-Western region of Russia. The results of the anisotropic inversion of CSRMT data are also compared with electrical resistivity tomography and hydrogeological data.
