Kutnohorite - Wikipedia

Kutnohorite is a rare calcium manganese carbonate mineral with magnesium and iron that is a meer of the dolomite group. It forms a series with dolomite, and with ankerite.The end meer formula is CaMn 2+ (CO 3) 2, but Mg 2+ and Fe 2+ commonly substitute for Mn 2+, with the Mn content varying from 38% to 84%, so the formula Ca(Mn 2+,Mg,Fe 2+)(CO 3) 2 better represents the species.
