Deformations, corresponding to processes of consolidation, deconsolidation and phase transitions in internal structures of the Earth

Questions of distribution of medium depending on changes of deformation have been studied involving various elastic potentials using non-classical linearized approach within the limits of theory of small and large initial deformations and it has been shown that this dependence for various geological media is instable. Given processes contribute to emergence of structures of formation deconsolidation zones. In presence of different kinds of inclusions, free and contacted surfaces and cavities the process of deformation occurs differently than assumed in experiments. Comparing the received theoretical results with results of 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 processes of phase transitions of various mineral systems.
