Abstract (in english)
   The Na Javorce Cave is located in the Bohemian Karst, Czech Republic, about 25 km SW of Prague. The cave was formed in vertically dipping layers of Lower Devonian limestone; it is 1,723 m long and 129 m deep, of which 9 m is permanently flooded. The cave is polygenetic, with several clearly separable evolutionary stages. Cavities discovered to date were mostly formed along the tectonic structures of two main systems. One of these systems is represented by vertical faults of generally N-S strike, which are frequently accompanied by vein hydrothermal calcite with crystal cavities. The second fault system is represented by moderately inclined west-dipping faults. Smaller tube-like passages of phreatic morphology connect the larger cavities. The fluid inclusion data obtained for calcite developed along both fault systems in combination with C and O stable isotope studies indicate that the hydrothermal calcite was deposited from moderately NaCl-type basinal fluids (0.5 to 8.7 wt. % NaCl equ
