Geochemical Peculiarities of Basalts of the Trostyanets Volcanogenic Complex (ukrainian Carpathians)

Year: 2011

Type: article

Abstract: Studies of magmatic rocks of the Triassic-Lower Cretaceous ophiolite association are of great significance for geodynamic re- constructions of the evolution of the Ukrainian Carpathians. These are almond-stone basalts, clasto-lavas of basalts, and dykes of trachytes in the complex of volcanic rocks of the Trostyanets Stream. Rocks are allochthonous and hence studies of their petrochemical and geochemical properties are of great importance. Volcanites belong to the K-Na series of rocks poor in ferrimagnesian and rich in lithophylic elements; they developed on the ensialic substratum. Results of studies of two-phase fluid inclusions in calcite indicate that the gas phase constitutes 10 to 25 vol. % and is represented by CH4 and its homologues - C2H6 ,C 3H8 and C4H10. These data may indicate a possible formation of carbon and hydrocarbons by means of the Fischer-Tropsch reaction of hydrocarbon synthesis.
