- Аннотация: Tourmaline is stable over a wide range of conditions from low temperature hydrothermal alteration to high grade and high pressure metamorphic environments, and magmatic conditions. It occurs in caprocks and salt domes, in granite and granite pegmatite, in the volcanic hosted massive sulphide deposits, in the porphyry-copper deposits, in metamorphosed stratabound Pb-Zn deposits, in mesothermal gold and tin deposits, in greisen tin and tungsten deposits, and schist-hosted emerald deposits. In this paper chemical substitutions, trace element compositions, and Fe3+/Fetot values, which allow distinguishing tourmalines from different hydrothermal deposits are reported.
