About KutnohoriteHide

Formula:
CaMn2+(CO3)2
Colour:
White, pale rose, pink, light to medium brown
Lustre:
Sub-Vitreous, Resinous
Hardness:
3½ - 4
Specific Gravity:
3.12
Crystal System:
Trigonal
Member of:
Name:
Named in 1901 by Antonín Bukovský for the type locality - Kutna Hora, Bohemia, Czech Republic.
Dolomite Group. Ankerite-Kutnohorite Series.

The cation ordering is temperature-dependent: Unpublished studies cited by Goldsmith and Graf (1960) indicate that cation disordering in synthetic CaMn(CO3)2 begins at approximately 450°C. CaMn(CO3)2 formed at higher temperature has a disordered distribution of Ca and Mn, and a calcite-type structure.
