Hydrothermal veins composed of quartz, calcite and tourmaline of schorl-dravite series are known from many localities in the Šternberk-Horní Benešov Belt, Vrbno Group and Konice-Mladeč Belt in the NE part of the Bohemian Massif. The veins are interpreted to have formed from fluids related to sub-seafloor hydrothermal systems in Devonian. In the southernmost part of the Šternberk-Horní Benešov Belt, fragments of quartz-calcite-tourmaline veins are very abundant at locality Babice. Apatite-(CaF) was found in a sole fragment of hydrothermal vein as white fan-shaped aggregates coating cavities after leached calcite (up to 0.7 mm thick crusts), and as up to 0.2 mm thick veinlets crosscutting quartz and tourmaline.
