Rhodochrosite from
N'Chwaning I Mine, N'Chwaning Mines, Joe Morolong Local Municipality, John Taolo Gaetsewe District Municipality, Northern Cape, South Africa
| Locality type: | Mine | |
| Classification | ||
|---|---|---|
| Species: | Rhodochrosite | |
| Formula: | MnCO3 | |
| Comments: | Numerous pockets of rhodochrosite crystals were found during the shaft sinking as well as mining with major discoveries in 1976-1978. The largest pocket measured 0.5 by 1.0 meter in size and produced a 100kg specimen. The red scalenohedrons were sold for 4 figure prices during the 1970's and 1980's.HabitsThe scalenohedral habit was relatively common and one could obtain single crystals as well as plates containing many crystals. The wheat sheaf habit consists of a central group of pale pink crystals becoming clearer and redder toward the terminations. Spheres of rhodochrosite are extremely rare, with a purported dozen specimens in total. Fan shaped aggregates are also believed to be extremely rare. Plate 64 from Wilson, Wendell.
