(Granulitaufschluss, Waldheim, Döbeln, Sachsen, Deutschland)

Outcrop of a hydrothermally altered granulite, located just east of the Waldheim freight depot. Today inaccessible.
Located about 10 km SW of Döbeln.

Prismatine from this locality was considered as Kornerupine for a long time, before it was eventually recognised as a new mineral. Older specimens, therefore, may still be labelled as Kornerupine. The latter, however, does not occur here.
