TI - The role of oxy-tourmalines and metasomatic mixing in evolution of lepidolite-subtype pegmatites
N2 - The lepidolite-subtype Lhenice pegmatite is a member of the South Bohemian pegmatite field in the is located in the southern part of the Moldanubian Zone of the Bohemian Massif, Czech Republic. We present results of textural and mineralogical analysis combined with data acquired using electron microprobe and LA-ICP-MS. The tourmaline in the Lhenice pegmatite shows apparently gradual evolution from the pegmatite border to its core from the most primitive to the most fractionated, with significant presence of oxy-tourmaline in all pegmatite zones. Tourmaline evolution is characterized by the crystallization of two primary tourmaline groups that, together with metasomatic generations, form the apparently continuous trend described by Selway et al. (1999). Study of the Lhenice pegmatite revealed complex evolution of tourmaline, mica and other accessory minerals that were very significantly affected by metasomatic and hydrothermal processes.
