Ancient lead-zinc mines, working irregularly distributed, vein- and lens-like, unmetamorphosed fluorite-galena-sphalerite mineralizations (rarely also fahlore) in dolomitized Triassic limestones of the Wetterstein formation.
Several adits, e.g., Viktor adit (Viktorstollen) and Friedrich adit (Friedrichstollen).
Fluorite crystals (colourless or violet) are mined by collectors.
Mining apparently already started during Roman times, later followed by activities in the 14th century until the early 17th century. An old adit was re-opened in the early 19th century but soon abandoned. No activity since 1920.
Located on Kühberg mountain near Obernberg.

|Paleozoic intrusive and metamorphic terranes|
Age: Paleozoic (252.17 - 541 Ma)
Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
Lithology: Intrusive and metamorphic terranes
