LTC pegmatite dyke at 2160 m, discoverd in summer 2009.
Discordant pegmatite body hosted in the migmatite gneiss of the Southern Steep Belt of the Central Alps. The dike, outcropping for 15 m, reaches 1.5 m in width. The foot wall of the dike has fine-grained layering border zone composed of K-feldspar, albite, quartz, and muscovite. The wall zone is composed of medium-grained (centimetre-sized) white perthitic K-feldspar, albite, flakes of silvery muscovite and quartz. The intermediate zone has medium to coarse-grained texture and consists of graphic quartz+K-feldspar, albite, muscovite, red millimetre-sized almandine-spessartine garnets, centimetre-sized prisms of pale blue beryl and graphic black schorl. The core zone of the pegmatite develops miarolitic pockets. In this zone a large pocket (1 m long, 60 cm wide and 50 cm deep) was found; it contained brownish-smoky quartz crystals, also with sceptre terminations, up to 15 cm in length, beryl var. aquamarine crystals up to 9 x 4 x 4 cm, pluridecimetric idiomorphic white perthitic K-feldspar, albite var. clevelandite as centimetre-sized laminar crystals, rare black schorl prisms up to 5-6 cm, and wodginite crystals up to 1.6 cm in length. The roof wall of the pegmatite is composed of medium-coarse grained K-feldspar, albite quartz, and abundant flakes of muscovite.
