Abstract (in english)
   Post-Variscan dolomites occur in Zn-Pb-Cu veins, Crush-leach, stable isotope (oxygen and carbon) and microthermometry analysis of the fluid inclusions in dolomites, Highly saline H2O-NaCl-CaCl2-MgCl2 fluids occur in inclusions, isotopic fluid composition indicate that the fluid was derived from evaporated seawater, rock-buffering explains the isotopic composition at low w/r ratios, fluid-rock interactions largely controlled the fluid chemistry (K, Li, Br and Na contents, K/Cl, I/Cl and Li/Cl molar ratios). A permeable basement and fractured sedimentary sequence enhanced the general nature of the fluid system. Fluid characteristics are comparable with the main post-Variscan fluid flow systems in the Polish (Cracow-Silesian ore district) and German sedimentary basins.
