Zankovych G. Geochemistry of fluids of veinlet-impregnated mineralization of promising oil- and gas-bearing complexes of the north-western part of the Krosno zone of Ukrainian Carpathians

Object of investigations: veinlet-impregnated mineralization; subject of investigations: fluid inclusions in minerals, mineral parageneses and typomorphic characteristics minerals and isotopic composition of Сarbon, Оxygen and Strontium calcite veinlet-impregnated mineralization; methods of investigations: field geoecological, mineralogical and ontogenesical, krystalomorfological, geochemical, thermobarogeochemical-mineraloflyuyidological; practical value: thermobarometry data and geochemistry of fluids veinlet-impregnated mineralization in perspective oil and gas deposits of the northwestern part of the Krosno zone in conjunction with geological and geophysical data will help clarify the prospects for oil and gas discovery and prediction of hydrocarbons within that structure-facies units of the Folded Carpathians; scientific novelty, revealed widespread veinlet-impregnated mineralization in the deposits of the northwestern part Krosno zone of the Ukrainian Carpathians, studied peculiarities of distribution veinlets and disseminated by laterallyu in the sedimentary strata, revealed their relationship with containing layers, thickness and stuff minerals; found that typomorphic mineral veins and inclusions are calcite; according to a detailed study of fluid inclusions in calcite veinlets and disseminations show compliance for the first time received the most widespread homogenization temperature (range 170-225 °C) temperatures veinlet-embedded in mineralohenezys to 200 °C, corresponding to the optimal preservation conditions of hydrocarbon compounds in the oil and gas sedimentary layer of the earth's crust; first established the composition of volatile components of fluid inclusions in calcite veinlets and disseminations, defined by the presence of only hydrocarbon components - methane and its first homologues (ethane, propane, butane); first identified the isotopic composition of Carbon, Oxygen and Strontium calcite veinlet-impregnated mineralization terrigenous complexes of the northwestern part of the Krosno zone, indicating the depth cow fluid source; eventually recreated fluid rate veinlet-embedded mineralohenezu and the chart depth migration of fluids of mineral deposits in the northwestern part of the Krosno zone of the Ukrainian Carpathians.
