THE SELF-ORGANIZATION PHENOMENONS UNDER PROGRESSIVE METASOMATISM OF CARBONATE ROCKS

The geochemical reason and types of self-organisation matter are examined on examples of rhythmic-banded metasomatic structures of progressive stage its mineral genesis as the consequence of thermodinamic non-equilibrium replacement by carbonatic rocks. The evolutionary development of mineralic rhythms in the time and in the space in shown; this is reflected in regular exchanges in composition of rhythmes in locks of zoned contact aureoles. The general sing for all those structures is the full abscence of facts about the crossing of mono-, bi- and poly-mineralic rhythmes in any its configurations. The experimental reproduction of metasomatic rhythmically-banded mineral aggregates is conducted. It is established, that the necessary and sufficient condition for origin of self-organization in metasomatites is the more large speed of successive-parallelic competing chemical reaction of fluids with wall-rocks than the speed of its infiltration in porous those locks (V-chr > V-inf. It is believe, that the genesis of rhythmic-banded metasomatites have been infiltrationic type and this is reflected in constant chemical composition of minerals in one composite bands. The diffusion effect have local character. Data about the postmagmatic changing of mineral composition in early metasomatites with preservation or lost its well regulated structures is given. The degree of thermodinamic non-equilibrium in metasomatism is reflected in the perfection of regulated mineral distribution. that will be lost in equilibrium systems. The origin of crustificationed or deposit (sedimental) rhythms formation is determined by the periodical achivement of oversaturation mineral-formed components in melts or solutions.
