Description
A shard of siliceous sulphide ore hosts a crust of sparkly chocolate-brown beudantite crystals (< 1 mm) supplanted by intergrown spherical sheaves of intensely pink smithsonite (to 5 mm; XRD verified, Paul Carr; University of Wollongong, April 2005). The colour intensity of the smithsonite is unusual as is the association with beudantite. The paragenesis is completed by a group of hollow epimorphs of cream-white dolomite (XRD verified) after what was almost certainly calcite (?).
The specimen was acquired from Ian Bruce in 2025 and is from an unnamed southern African collection. The location in the mine is not recorded but the specimen is probably from the second or third oxidation zone.
