NUMERICAL MODELLING OF THE METAMORPHIC MINERAL
SOLUBILITY IN HYDROTHERMAL SOLUTIONS AT 400-800°C, 1-5 KBAR
AND VARIOUS FLUID ACIDITY
S. Bushmin, P. Azimov, S. Lvov
This paper discusses the character of dissolution in aqueous fluid for the 56 usual minerals of metamorphic rocks depending on the PT-conditions and fluid composition. Computer modelling of mineral-fluid equilibria carries out the study of solubility. The calculations are accomplished for both pure water and solutions, containing acid (HCl) and alkali (NaOH). We distinguish the seven basic types of the solubility diagrams in dependence of peculiarities of mineral behaviour in acid and alkaline solutions. For most minerals, excepting Qtz, Mi, Ab and Jd, the solubility value is determined mainly by fluid acidity (pH) and weakly by P-T.
Analysis of the mineral solubility allows to characterize the element mobility depending on the fluid acidity. The most mobility is manifested by Si, K and Na independent of fluid acidity. Ca and Mg are most mobile in acid solutions whereas Fe(II) is mobile in both acid and alkaline fluids. Al is rather immobile element and is transferred mainly in alkaline or strongly acid solutions. The most immobile is Fe(III) – i.e. iron is transferred mainly as Fe(II). Therefore, change of fluid acidity results in dissolution of some components and precipitation of other ones. Minerals of different types could be indicators of the fluid acidity
at metasomatism. Since high solubility of quartz most metamorphic fluids should be silica-saturated. They should also contain significant amount of alkalis. The decrease of P and T can leads to origin of supersaturated silica-alkaline fluids producing metasomatism in country rocks. The solubility of Fe-, Mg- and Ca-bearing minerals is low in alkaline fluids in comparison with acid ones. Hence only primarily acid fluids can produce solutions, enriched in these elements, at their leaching from country metamorphic rocks. Fluids, enriched only in Fe, could have initially both acid and alkaline character.
Key words: minerals solubility, fluid, metamorphism, thermodynamic modelling, fluid acidity, element mobility.

HYDROTHERMAL MINERALOGICAL ZONING AND METAMORPHISM
IN LOWER VENDIAN COPPER-BEARING TRAPS
OF THE VOLYN’-PODILLYA PLATFORM

The zone spatial distribution of hydrothermal minerals associations has been revealed in the Lower Vendian trap formation of the Volyn’-Podillya platform. Carbonaceous, zeolite and prehnite concentric zones have been allocated, which consecutive change can be looked after from edges to the centre of the trap province. These zones definitely supervise distribution of native and sulphide types of copper mineralization in traps and have different perspectives on copper. Vertical symmetric mineralogical zoning in basalt flows has caused conditions of native copper localization in zeolite zone. On typomorphic mineral associations, the degrees and scales of rocks recrystallization, and also temperature parameters of mineral forming, zone hydrothermal-metasomatic changes of traps correspond to zeolite and prehnite-pumpellyite metamorphic facies. The assumption is stated, that by the origin they are obliged to mineralized underground waters of Horbash³vs’kyi waterbearing horizon. Probably, these waters were warmed up from below by numerous gabbro-dolerite sills, which were intruded at the end of the Early Vendian near to bottom of this horizon at the centre of the Volyn’-Polissya trough.
Key words: copper deposits, traps, hydrothermal minerals, mineralogical zoning, metamorphic facies, Vendian, Volyn’-Podillya platform.

Thermobaric and isotopic parameters of mineral-forming fluid components of graphite and gold deposits from carbon-bearing parametamorphic rocks of the Ukrainian Shield have been studied. Host rocks are the main source of fluid components. Carbon dioxide is the dominated component of mineral-forming fluids gases. The conclusion has been made that carbon of CO2 was derived from oxidized organic matter, rarely from decarbonized limestones. Isotopic composition of hydrogen of water was changed as the result of interchange among water and other H-containing compounds of fluid, possibly H2S.

The mineral composition of insoluble residue pelitic fraction of Miocene salts and their weathering zone (gypsum-clay caprock) of Kalush-Holyn’ deposit has been researched by the diffractometer method. Clay minerals of salt deposits are represented by hydromica and chlorite; gypsum-clay caprock contains also kaolinite and mixed-layer hydromica–montmorillonite. So during long time salt deposits leaching by superficial water on the hypergenese stage the kaolinite formation and potassium loss by hydromica and it transformation in mixed-layer hydromica–montmorillonite take place – the last is hydromica degradation process.

At 86°C the crystal structure of schoenite begins to destroy and leonite is formed. Heating to 100°Ñ leads to dehydration of leonite and possibly formation of double-aqueous salt K2Mg[SO4]2·2H2Î, which destroys at the temperature near 150°Ñ, and from these products langbeynite and arkanite form (stable at 250°Ñ).
