Abstract (in english)
   Monazite, as the main carrier of U and Th in host biotite gneiss at the Rožná uranium deposit, was replaced by allanite during the process of partial melting. This transformation as accompanied by a release of U, and to a lesser extent of Th, from the monazite lattice. The liberated U and Th crystallised in the extracted granitic melt mainly in the form of thorogummite or cheralite. The granites are depleted in HFS and LREE. Garnet-poor granites are depleted in HREE as well, whereas garnet-rich types are enriched in HREE
