Abandoned graphite quarry with pegmatite outcrops.
Several workings extend from the quarry along the ridge towards the E and SE (i.e., towards Trandorf). Some of them have individual names, e.g., Weinberg (workings on Weinberg Mt, 741 m asl), Corundum Ditch, Red Lake, etc. (for "Turquoise ditch" see sublocality "Weinbergwald")
Located west of Mühldorf.
See also the localities Trandorf and Wegscheid which belong to the same graphite mining district.

1600 - 2500 Ma
|Paleoproterozoic intrusive and metamorphic terranes|
Age: Proterozoic (1600 - 2500 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
