Shattuckite


Mineral: Shattuckite, Dolomite
Chemistry: Cu5(Si2O6)2(OH)2
Size: 60 mm
Owner: W.W. (Bill) Pinch

A rich, botryoidal crust of radiating microcrystals of shattuckite on an iron-stained rock matrix.  The colour of the shattuckite ranges from sky-blue to cyan-blue, and sparse aggregates of milky-white dolomite rhombs on the shattuckite provide a pleasing contrast.

Shattuckite is a rare mineral at Tsumeb, though relatively common from other localities in northern Namibia.  Gebhard (1999) notes that shattuckite occurs sparingly throughout the Tsumeb deposit but, unfortunately, the level from which this specimen originates is not recorded.
