Role of dissolution-reprecipitation in deciphering mineral evolution trends in lepidolite-subtype pegmatites
Original language description
The lepidolite-subtype pegmatite at Lhenice is a member of the South-Bohemian pegmatite field, in the southern part of the Bohemian Massif. The Lhenice pegmatite forms flat-laying tabular body ca. 4 m thick and 20 m long in its most fractionated part. The dike has concentric zoning (from border to center): graphic zone, granitic zone, Qtz-Ms-Ab zone and Ab-Lpd zone. Textural analysis and mineralogy of the pegmatite indicate a complex crystallization history, with initial potassic melt followed by (auto)metasomatism by Li,B,F-rich sodic melt and final alteration by Li,F-rich immiscible liquid phase. The new results show that the evolution trend in this type of pegmatites can be distorted by common dissolution or recrystallization of early minerals by later events. We present results of textural and mineralogical analysis combined with data acquired using electron microprobe and LA-ICP-MS.
