XQ2-KQVPrehnite : Ca2Al2Si3O10(OH)2

Multiple photos available
Goboboseb Mts, Brandberg Area, Dâures, Erongo Region, Namibia

Dimensions: 13.5 cm x 7.5 cm x 2.5 cm

This is a very fine large prehnite from the Erongo Region of Namibia. It has characteristic form that makes me think it might be from the Kudikop area, but there is no firm documentation for this. Form is different than the calcite/quartz/prehnite specimens usually seen from Namibia.
