| Résumé: | Заглавие с экрана Developed by D.S. Korjinsky on the thermodynamics laws fundamentals the theory of the endogenous metasomatic zoning in near-vein itsvariant discovers and explains the structure of the metasomatic columns including reduction of the minerals and components number on onein every more rear zone right up to monomineral rear zone, in acid metasomatites – quartz vein. According to the theoretic script it is achievedby means of solution of the minerals and transition of the components from inert to mobile condition (in solution). The components diffusesfrom pore solution into fissure and as result move away from system of the metasomatism, except SiO2, which forms quartz vein.According to the natural script as result introduction in fissures hot metal-bearing solution it is formed fissure-pore rock-fluid systemin which head diffusion of the components is arised from pore solution to fissure and from fissure to pore. Almost all Na and to 50 mass.per cent from initial content Si move away from wall rocks (to 1,5 t from 1 cubic metre). Other components of initial rocks are redistributedbetween mineral zones of forming metasomatic columns. Simultaneously K, S, CO2, in the frame of deep faults femic elements Mg, Ca,Fe, Mn, P, Ti steady receives with fissure solutions and diffuses in pore solutions of the wall rocks, where they are fixed into compositionof the sericite (K), carbonates (CO2, Ca, Mg, Fe, Mn), oxide (Ti), phosphate (P), sulphides (S, coloured metals) mainly into quartz veins andrear zones of the near-vein metasomatic columns. In this conditions formation of the monomineral rear zone into metasomatic columnsof the beresite petrochemic profile of the ore deposits impossibly. In adjacent with metalliferous quartz vein rear zone of the metasomaticcolumns is formed metasomatit – polimineral beresite in the composition of the quartz, sericite, Mg-Fe carbonates, sulphides, rutile,leucoxene, apatite, magnetite. It is obvious that in the appraisal of the theory priority belong to natural mineral-petrochemic zoning. Since following out of theorymodel of zoning is not coordinated with the latter (inadequate it) it,s necessary to improve or to develop modern theory provided that allfactors determining metasomatic zoning and influencing on it be take into account.In correction of the theory following proved conditions are taken into account: 1) thermodynamic and physicochemic regimes insystems of the near-vein metasomatism and its evolution; 2) pulsation (portion) regime of the functioning of hydrothermal rock-oreformingsystems; 3) stagnant regimes fissure and pore solutions into fissure-pore rock-fluid systems of the metasomatism; 4) mechanism of themasstransportation in processes of the near-vein metasomatism is concentration diffusion; 5) head diffusion of the components from poresolution into fissure and from fissure into pore solution. |
