DOUBTFULL FLUORESCENCE but cited by some authors
Chemical Formula: Ca(Mn+2,Mg,Fe+2)(CO3)2
Mineral for Display: No
Associated names (luminescent varieties, discredited names, synonymes etc.): kutnahorite,
|Long Waves (365nm): || Red ||Short Waves (254 nm): || Red |
Phosphorescence (in the common meaning of the term) seen by naked eye:
Doubtful: many samples could be calcite containing Mn or the fluorescence may result from intermixed manganoan calcite
Main Activator(s) and spectrum:
Best Locality for luminescence(*):
- Wessels Mine, Hotazel, Kalahari manganese field, Northern Cape Province, South Africa (but the fluorescence may result from intermixed manganoan calcite);
- N'Chwaning Mines, Kuruman, Kalahari manganese field, Northern Cape Province, South Africa ;
- Sterling Mine, Sterling Hill, Ogdensburg, Franklin Mining District, Sussex Co., New Jersey, USA ;
(*)Data are not exhaustive and are limited to the most important localities for fluorescence
