Abstract (in english)
   Variscan granitoids of the western part of the Bohemian Massif are represented by three groups of granitoids which differ in their age, texture, mineral and chemical composition. The oldest group is represented by a suite of metaluminous granodiorites to diorites and is the precursor of the younger metaluminous/peraluminous granites. The remaining two groups of monzogranites comprise magmatic suites described by gradual increase of the Rb/Zr, Rb/Ba and U/Th ratios and decrease of the LREE/HREE ratios. The most plausible model for the genesis of granitoids in the western part of the Bohemian Massif is the one of an oblique collision of single blocks of the earth crust along the West Bohemian shear zone and subsequent thickening of the earth crust in this area
