Malachite and Calcite on Dolomite (Tsumeb, Namibia)
Tsumeb Mine, Otjikoto Region, Namibia. 40mm x 35mm x 10mm.
One the one side of the Dolomits cast one finds it covered in little Calcites that are a very very light shade of green. On the other side of the cast the Calcites are very well associated with Malachite, some have overgrown the malachite and in other cases the Malachite is still unaltered. It's a fun specimen from a really special locality.
