Abstract
The lepidolite-subtype pegmatite at Lhenice is a member of the
South-Bohemian pegmatite field (Novak & Cempirek, 2010); the
nearest rare-element pegmatites include Lhenice II, Nova Ves
and Chvalovice I and II. All pegmatites are characterized by
high Li and P contents and similar mineral composition
(elbaite, schorl, biotite, K-feldspar, lepidolite). The Lhenice
pegmatite is moderate-sized and highly fractionated, with
abundant lepidolite, elbaite, amblygonite and cassiterite.
Tourmaline samples were analysed using EMPA and LA-ICP-MS.
Primary, metasomatic and recrystallized tourmaline generations
were characterized.
