The Lekbachschart area contains numerous Alpine type veins which contain quartz crystals, adularia
, and anatase
as well as diverse beryllium minerals (white and blue beryl
, beryllian margarite
, and milarite
) and scheelite segregations.
Transparent yellow phenakite
crystals, up to 10 cm in length, occur with light-coloured beryl
in lenses of biotite-chlorite rocks within talc schists.
