his diverse mineral forms in many colours and crystal shapes. Calcite is one of the most common minerals, and has been found at all the mines of the Kalahari Manganese Fields. It is found lining the veins and vugs in the Manganese ore beds.
Calcite forms in a variety of crystal habits, including rhombohedra and dog-tooth Calcite. Many of the specimens are clear, but pink Manganoan Calcite has also been found. The Calcite crystals are often fluorescent under Ultra Violet light, especially the Manganoan Calcite, which fluoresces an intense red.
There have been some interesting twinned formations, and double terminated crystals found.
Calcite is commonly associated with many of the minerals of the Kalahari Manganese Fields, including Pyrite, Andradite Garnet, Hematite and Hausmanite, as well as many of the rare minerals.
