Abstract (in english)
   Heterogenous composition of dioritic intrusions in the Slavkovský les is explained by mixing between mafic and felsic magmas with a minor effect of fractional crystallization. Single zircon Pb evaporation analysis constrain the age of monozodiorite at 323 Ma and of a granodiorite at 326 Ma. The P-T range of magma crystallization is estimated at 1,4 -2,2 kbar and 730 - 870° C.
