Description

Set of brown to red sphalerite crystals on massive sphalerite from the Beauraing mine in the eponymous locality near Namur, Belgium.

The Beauraing mine exploited a breccia vein of galena with sphalerite as an associated mineral, the latter often being more abundant than the sought-after lead-based ore. The ore was emplaced during a post-Variscan period and filled fractures formed in the Givétien.
