Tourmaline geochemistry in the granitoids of the Sanandaj–Sirjan Zone (A case study of Astaneh and Aligudarz granitoids) [PDF]
پترولوژیIntroductionTourmaline exhibits a broad range of chemical variability (Hawthorne and Henry, 1999). This diverse and complex chemistry reflects a clear genetic link between tourmaline and the environment from which it crystallized.

Crystal chemistry of the schorl-dravite series
European Journal of Mineralogy, 2004 Nineteen tourmaline samples of various provenances and geological settings were studied by EMPA, SREF and MS to represent the schorl-dravite compositional field. All samples belong to the Alkali group (except one with an X -site vacancy content of 0.53 apfu) and to the Oxy- and Hydroxy-subgroups. Among divalent cations, the main substitution involves
