Abstract

V originále

Hydrothermal veins occurred in the Lower Carboniferous siliciclastics of the Drahany and Zábřeh Upland. The older vein system, most likely late Variscan, has mineral assemblage: quartz ą calcite ą chlorite ą sulphides (pyrite). Minerals display a severe deformation and calcites are fine grained with a low intensity of cathodoluminescence. Post-Variscan generations of veins have the mineral assemblage with calcite - barite - sulphides (sphalerite, galena, chalcopyrite, pyrite-markazite) ą quartz ą fluorite ą siderite. The main post-Variscan population of calcites precipitated from solutions of H2O - NaCl ą CaCl2 ą KCl ą MgCl2 ą FeCl2 type under low temperatures within a range of 60-90C. One of the younger aqueous hydrothermal systems contain also higher liquid hydrocarbons. Isotopic composition of parent fluids were about values of d18O from 0 to 10 SMOW, what is indicative for transformed basinal brines originated from sea or partly meteoric waters.
