Mineral Specimen #6734    Dolomite Pseudomorph/Epimorph after Descloizite

Berg Aukas Mine, Grootfontein, Otjozondjupa Region, Namibia

10.5 x 9.5 x 7.4 cm
4.1 x 3.7 x 2.9 in


Ex. E. Morales from J. Minette, Nov. 1983

A very unusual pseudomorph in which small, well formed Dolomite crystals have partially replaced Descloizite crystals. In most places, there is still Descloizite present underneth; but elsewhere, the Descloizite has dissolved leaving a cast with an epimorphic layer of Dolomite crystals. The Dolomite is off white in color with a light hint of orange in places. The underlying Descloizite is an orange brown color. The location is quite famous for Descloizite specimens, some of which can have small Dolomite crystals growing on them. This piece is quite unique due to the pseudmorphism.

Condition: Excellent

Flaws: Nothing Appreciable
