Picture 2 – Topographic map of UGCC site
During the second developmental stage (Miocene period) downwarping became slower resulting
in the minor thickness of the bed (25-250m) relating to this period. Later tectonic movements having low
gradients of vibrations and predomination of the total rising effect turned the area in question into
plateau.
Geological structure has two geological engineering rocks complexes:
1) Argillo-marlitic complex of deposits from Palaeogene period (terrigenous-carbonate
formation – group of semihard rocks) presented with carbonate rocks, predominantly
marls. Limestones and argillas have minor spreading and sandstones are very rare.
