Azurite, (w. Malachite)


Mineral: Azurite
Chemistry: Cu3(CO3)2(OH)2

A sub-spherical concretion of royal-blue azurite (32 mm), transected by a vein (or fracture-fill) of malachite.

This specimen was presented to Professor Charles Palache as a “Gift of [Wilhelm] Klein” to the Shaler Memorial Expedition”.  The accompanying label describes it as “Azurite ball from clay”, similar, perhaps, to some of the material recovered by the specimen mining operation on 5 Level in the early 2000s.

(Palache was a member of the Shaler Memorial Expedition to South Africa, in 1922.  Officially, the expedition did not visit South West Africa, however, Palache broke away from the official party to visit Tsumeb in early April, 1922.)
