(Loja, Persenbeug, Waldviertel, Niederösterreich, Österreich)
Quarry in complex regional-metamorphic rocks (paragneisses, amphibolites, silicate marbles, graphite marbles; kersantitic and diorite-porphyritic veins).
Located ENE of Persenbeug, in the narrow Loja valley.
The quarry area formerly consisted of three quarries (one left of the road, two right of the road); nowadays there is only one big quarry on the right side.
[Detailed work on mineralogy in prep. (Löffler & Kolitsch); currently (2009) roughly 50 species have been confirmed, based on numerous analyses.]
