Abstract (in english)
   Within the central part of the South Bohemian Pluton three strongly peraluminous granite intrusion events were recognized. All three events were defined in their surface extension and can be distinguished by their individual mineralogical and geochemical features. The oldest one, the Lásenice granite, was produced by minimum melting of metasedimentary material during the thermal peak of the Variscan metamorphism. The main stage of intrusion history is represented by the suite of the Číměř, Eisgarn, and muscovite granites. The original high-K peraluminous melt, which was rich in Zr, Th and REE, underwent an intensive fractionation process towards the enrichment in Na, P, F, Li, Rb, Sn, Nb, U and Ta. The last melting episode produced deep seated stocks of Zvůle type. This melt was evolved in case of major elements, but contrast to previous melt, not able to produce LILE and Sn, Nb, U, Ta-enrichment
