Evolution of topaz-bearing granites in the Krásno and Vysoký Kámen area (Slavkovský les Mts.)
René, Miloš ; Kempe, U. ; Wolf, D.
In the area between Krásno and Vysoký Kámen, southwestern of Karlovy Vary some stocks of topaz-albite granites are evolved, which are part of the Krudum granite massif. The Krudum massif has a markedly zoned internal structure with the oldest porphyritic biotite granites in its central part and younger two-mica granites and topaz-albite granites on its periphery. Topaz-bearing granites are evolved by means of progressive fractional crystallization from peraluminous granite melt.
