Bultfonteinite with Apophyllite-(KOH) and Calcite
N'Chwaning II Mine, Kuruman, Kalahari, South Africa
42mm x 37mm x 21mm
Fanlike groups of snowy white acicular crystals of Bultfonteinite replacing the faces of short elongated crystals of Apophyllite-(KOH) which has a pseudocubic habit. In some cases the replacement is deeper and forms a more or less complete pseudomorph of the preexisting Apophyllite-(KOH). All are on a matrix of clear, complex, crystals of Calcite. Well send a copy of the analysis to the buyer of the piece.From: Fabre Minerals
