Kutnohorite

Carbonate mineral

Kutnohorite is a rare calcium carbonate mineral that is a member of the dolomite group. It forms a series with dolomite. The end member but Mg2+ and Fe2+ commonly substitute for Mn2+, with the Mn content varying from 38% to 84%, so the formula Ca(Mn2+,Mg,Fe2+)(CO3)2 better represents the species. It was named by Professor Bukowsky in 1901 after the type locality of Kutná Hora It was originally spelt “kutnahorite” but “kutnohorite” is the current IMA-approved spelling.
