Abstract (in english)
   A mineral association with dominant pyrrhotite, tsumoite and gold, accompanied by minor tetradymite and pilsenite, has been found in material from the main vein of the abandoned Au deposit Libčice near Nový Knín, 25 km SSW of Prague, central Bohemia, Czech Republic. Tsumoite forms abundant silvery-grey tabular aggregates up to 1-4 mm in size. The studied mineral association formed at elevated temperatures (>300 ? C), probably in the course of two stages differing in bismuth activity, as well as fS2 and fTe2 values. Alternatively, the two stages could have reflected variation of hydrothermal and metamorphic process in space and time.
