and increased permeability in places disturbed by cryodynamic and thermody-
namic processes are usually observed. These signs indicate relatively high dynamics
of liquid and solid phases of the geological medium and increased activity of geo-
chemical processes within the central parts of active depression forms.
In the study of the structural elements and the whole PFMZ structure of the
cover deposits (to a depth of 10 m), the ground-penetrating radar (GPR) SIR-2
with a 300 MHz antenna was used. In the result, the sections were obtained with
detailed reflection of horizontal and vertical heterogeneity (Figure 3.9).
