Tourmaline supergroup minerals are the most important minerals of boron worldwide. Gemeric superunit in the Eastern Slovakia is rich in occurrences of tourmaline in various geological environments. They belong to common gangue minerals in Sb-hydrothermal deposits. Analysed samples were taken from stack material, originated from Čučma-Gabriela, Rožňava-Grexa, Rožňava – Peter-Pavol and Betliar-Straková vein deposits. Tourmalines from these deposits forms relatively large (up to several cm to dm) parallel to radial aggregates of, black – greyish-black prismatic crystals. Analyzes from electron microprobe, as well as BSE images of these samples show differences in composition and thus conditions during evolution of tourmalines between groups A – Čučma-Gabriela & Rožňava-Grexa; and B – Rožňava – Peter-Pavol & Betliar-Straková. Based on results, tourmalines from the group A were enriched in Al during evolution, in contrast position X was depleted, in case of sample from Čučma-Gabriela transition to magnesio-foitite composition took place during second stage of crystallization. In case of group B, the depletion in Al took place during crystallization and at the same time, position X was enriched in Ca, Na and minor K. Dominating substitutions in group A was uvite Ca(Mg,Fe2+)NaAl-1 to alkali-deficient X□AlNa-1(Mg,Fe2+)-1 substitutions, in case of Rožňava-Grexa, there is inclination to proton-deficient AlO(Mg,Fe2+)-1(OH)-1 substitution visible. Tourmalines from group B are dominantly controlled by the alkali-deficient X□AlNa-1(Mg,Fe2+)-1 substitution. It is clear from XRD data, that studied minerals involve relatively large Al-Mg disorder accompanied by ZFe3+ which is documented by relatively large c unit-cell parameter. Raman spectra showed stronger intensity of O-H vibrations in position V and weaker in position W.
