Given processes contribute to e mergence of structures of formation deconsolidation zones. In p resence of different kinds of inclusions, free and contacted surfaces and cavities the p rocess of de formation occurs differently than assumed in experiments. Comparing the received theoretical results with results o f known experimental studies, it has been shown that the processes of loss of stability of elastic state of equilibrium on geometric shape change and on "internal" instability precedes the p rocesses of phase transitions of various mineral systems. |
