Abstract (in english)
   Integration of geochemical, mineralogical, isotopic, and geochronological data with geodynamic consideration suggests that the Variscan granites in the Erzgebirge-Slavkovský les domain originated from repeated melting events and were emplaced over a period of about 40 Ma (330-290 Ma). Several lines of evidence exist supporting the idea that erzgebirge granites assigned to different types (biotite granites, two mica granites, strongly peraluminous P-ric Li-mica granites, and slightly peraluminous P-poor granites) are in most cases not genetically related via continuous fractional crystallization from a common magmatic reservoir. The genesis of the Slavkovský les granites, however, might be discussed in terms of an uniterrupted fractionation series.
   Geological models of Sn-W deposits based upon geochemical and structural results imply that the main ore depositional events followed immediatelly the emplacement and solidification processes of melt via fluid-melt immiscibility, breccia-pipe formation and/or pervasive rock-fluid interactions
