Abstract
Tourmaline is a polygenetic mineral and often occurs in pegmatite and pneumatolyte‐hydrothermal (metasomatic) and metamorphic rocks as a rock-forming mineral [1]. Wide varieties of the tourmaline chemical composition, often within the limits of even one deposit, make it a good indication of the changing physicochemical conditions of mineral formation. Crystals of tourmaline formed in rare metal pegmatites, greisens, and hydrothermal veins are characterized by the extremely great varieties of composition. More than 14 mineral varieties of tourmaline have been identified [2], which is connected with the peculiarities of its structure. Its generalized crystal chemistry formula is the following: XY 3 Z 6 Si 6 O 18 (BO 3 ) 3 V 3 W , where X— Na + ,
