N2 - Induced polarization of anisotropic models with metallic particles G. Gurin*(SPbSU, “NPP VIRG-Rudgeofizik” Ltd.), Yu. Ilyin (SPbSU), and K. Titov (SPbSU) Summary We studied an effect of anisotropy of induced polarization parameters (the total chargeability and the relaxation time) with 22 synthetic models containing rounded, rod-like, and plate-like electronically conducting and semiconducting particles. We carried out the measurements in time domain with a commercial AIE-2 instrument and a low-current laboratory transmitter with various direction of the polarizing field relative to the model anisotropy axis. We found the total chargeability of the models contained rod-like particles strongly depended on their size and direction of the polarizing field. In contrast, for the models contained plate-like particles these dependences are week. These relationships can be described with a modified Maxwell-Garnett equation. We found the relaxation time of the anisotropic models depended on the model composition, the pore water electrical conductivity and the half of the particle great axis. In addition, the relaxation time weakly depended on the direction of polarizing field relative to the direction of anisotropy of the models.
