The author proposes that the described phenomenon can occur under the effect of a mechanical energy flow through aligning of defects (nonconductive channels for this flow) along field force lines. A mechanism of discontinuous self-decomposition of geomaterial under the effect of rock pressure, i.e. external power source, was developed basing on these effects. Another thermodynamics is needed to explain the CNF (cold nuclear fusion) phenomenon which would be based on balance of in- and out-flows of energies (balance of sinks and sources) rather than on conservation laws.
