Kabwe Mine (Broken Hill Mine), Kabwe (Broken Hill), Central Province, Zambia
Thumbnail, 2.6 x 2.2 x 1.7 cm
A fine thumbnail specimen of the rare zinc phosphate Tarbuttite which is loaded with sharp, transparent to translucent, colorless triclinic tabular crystals on gossan matrix. The largest crystal measures 8 mm, which is good size for Tarbuttite. The Broken Hill mine (also called the Kabwe mine), in Zambia, not Australia, is the type locality for Tarbuttite, and has certainly produced some of the finest specimens of the species extant. Ex. Richard Kosnar Collection.
