Dolomite, (after Wulfenite)

Mineral: Dolomite, Wulfenite
Size: 160 mm
Owner: Jim Robison
Photographer: John Schneider

An aggregate of randomly orientated crystals of wulfenite (to 30 mm) has been completely encrusted, and partly replaced, with off-white dolomite.

Partial crusts of dolomite on wulfenite are not uncommon at Tsumeb, but this degree of replacement is rare, and this is a large and very well-preserved example.
