Nesterovych N. Geochemistry of fluids of formation medium of copper-bearing parageneses in volcanites of the trappean formation of areas of junction of the Volyn Paleozoic uplift with the Volyn-Podillya monocline

Object of investigation: Lower Vendian trap formations and associated with them copper-bearing mineral paragenesises; subject of study: petrography, geochemistry, petrochemistry, mineralogy, mineralfluidology of rock-ore complexes trap formations of junction of the Volyn Paleozoic uplift with the Volyn-Podillya monocline; methods of investigation: field geological, petrographic, geochemical, mineralogical, mineralofluidological studies; practical value: it was established of ore-bearing and barren horizons within the study area, explained the reasons for localization in certain areas trap formations industrial copper-bearing mineralization due to process of liquation, extraction and transfer of copper in upper part flood and deposition of dispersed precipitates of native copper on the geochemical barriers, that may be used for prediction and search for new native copper object within the study area, received results will make it possible to apply this approach to all trap formations, located in Western Volyn; scientific novelty: it was established a direct relationship between the power of effusions and copper concentrations on the basis of the constructed maps of power and relief, wells sections of suite and strata stratified all district units; the presence of liquation phenomena in the course of the trap formation generation that contributed to separation of the copper droplets with transference into near-surface horizons of outflows was proved; the genetic significance of findings of pisolithes in tuffs of the Babyn suite was determined, systematic mineralofluidologic study of volcanites were carried out as well as the temperature, composition and aggregate state of the fluid environment of crystallization of minerals of the copper-bearing paragenesises were determined, possible mechanisms of the copper transference and localization at proper levels of lavas formations were proposed; sphere of use: geochemistry of the trappean formation volcanites.
