Many TEM data from Yakutia and other areas of widespread permafrost bear a manifestation of the induced polarization (IP) effect. The distinguishing feature of this effect is the distortion in the monotony, sign reversals included TEM voltage responses in the time range from a few tens to a few hundreds of microseconds. According to the inversion of TEM responses in terms of the Cole-Cole conductivity model, the IP effects are produced by fast decaying polarization in the upper 100 m of frozen ground. Shallow frozen rocks exhibit the chargeability m in the range 0.2 to 0.85, mostly within 0.2-0.5, the relaxation time tau from 35 to 250 mu s (50 to 100 mu s on average)
