Epigenetic organic and inorganic associations are described for, and express the thermo-baric conditions of, the stability of the whole coal deposit from the Armenis area. The thermo-baric conditions in which natural coke, pyrocarbon, and semi-graphite were generated correspond to a maximum of 300 C and one kbar. These new thermo-baric conditions are pointed out by the mineralogic equilibrium: kaolinite + quartz = pyrophyllite + water, which exist in the meta-anthracites and meta-sandstones. This equilibrium is specific for anchimetamorphisms of the Armenis meta-anthracitic coal deposit. The anchizone characterizes many Lower Liassic deposits from the Alpino-Carpatic Range Mountains.
