| Description | A nomenclature for tourmaline-supergroup minerals is based on chemical systematics using the generalized tourmaline structural formula: XY3 Z6(T6O18)(BO3)3V3W where the common ions at each site are X = Na1+, Ca2+, K1+ and vacancy; Y = Fe2+, Mg2+, Al3+, Li1+, Fe3+ and Cr3+; Z = Al3+, Fe3+, Mg2+ and Cr3+; T = Si4+, Al3+ and B3+; B = B3+; V = OH1- and O2-; and W = OH1-, F1- and O2-. Most compositional variability occurs at the X, Y, Z, W and V sites. |
