earthstory:

Kutnahorite

Calcium carbonate is well known as calcite or aragonite, but forms what is called a solid solution series in which iron and manganese can substitute for calcium in the crystal structure forming mineral end members known as dolomite (magnesium), ankerite (iron) and kutnahorite (manganese). The type locality is the town of Kutna Hora just outside Prague in the Czech republic

Manganese usually makes for lovely pinks or reds, and the bright pastel colour of this 4.4 x 4.2 x 1.9 cm specimen from Wessels mine in South Africa is typical of the genre. Kutnahorite can also be white or light brown (as the iron content increases). It shares the perfect rhomobohedral cleavage of calcite, and occurs in manganese rich sediments and altered ore deposits. It is found in Italy, Colorado, Japan and South Africa.
