Abstract (in english)
   Tourmaline is an accessory mineral of the Late Palaeozoic granites of the Krušné hory-Erzgebirge batholith (290-330 Ma). Its occurrence is distinctly regionally dependent; it is common in the Western pluton of the batholith and extremely rare in granites of the eastern pluton. Very low constent of Mg and Fe in granites cause the rare occurrence of tourmaline in the pluton in spite of a high content of boron in granite melt, e.g., in Blatná granite body. The magmas themselves were incapable of conserving much born as displayed by the occurrences of tourmalinized phyllites and tourmalinites at contact of this body. All the tourmalines examined correspond to schorl-dravite series with a low content of uvite component, expecially in metasedimentary rocks. A higher concentration of fluorite in tourmaline is in greisenized granites, whereas the lowest contents were found in tourmalines occurring in wolframite-quartz veins at Rotava.
   Thus the chemistry of tourmalines indicates the conditions of their crystallization
