Tourmalines, common accessoryminerals in granitic rocks, typically exhibit a wide spectrum of chemical compositionsand compositional ranges in pegmatites affiliated to LCT-family; tourmalinesfrom NYF pegmatites were only infrequently examined (e.g., Novák et al. 2011).Furthermore, most studies are focused on primary (solidus) tourmalines and ontourmalines from exo/endocontacts, whereas tourmalines from fractures and fromsubsolidus replacement assemblages were examined only sporadically.
