Ankerite - Wikipedia Ankerite, also known as brown spar [5]: 258 (German: braunspat) is a calcium, iron, magnesium, manganese carbonate mineral of the group of rhombohedral carbonates with the chemical formula Ca (Fe,Mg,Mn) (CO3)2
Ankerite: Mineral information, data and localities. - mindat. org Named after Matthias Joseph Anker (1771-1843), Austrian mineralogist Originally considered to be Ca (Mg,Fe) (CO 3) 2 (eg Hey, 1955, with >10% FeCO 3) with no specific requirement for Fe>Mg, before being redefined as strictly having Fe>Mg, i e with the dominant endmember CaFe (CO 3) 2
Ankerite – Mineral Properties, Photos and Occurrence Ankerite is a calcium-iron carbonate with ideal chemical formula CaFe(CO 3) 2 Ankerite is a member of dolomite group and often contains significant amount of dolomite (Mg) and kutnohorite (Mn) component Pure ankerite was never identified in nature, it always contains impurities
Ankerite Mineral Data Common in ore-bearing rocks as a rock forming mineral (gangue) High Fe species are found in iron ores Styrian Erzberg, Eisenerz, Styria, Austria Link to MinDat org Location Data Named after the Styrian (Austrian) mineralogist, Mathias Joseph Anker (1771-1843)
ANKERITE (Calcium Iron Magnesium Manganese Carbonate) - Amethyst Galleries Ankerite is named after Professor M J Anker, an Austrian mineralogist Ankerite's formula is often written as CaFe (CO 3) 2; but there is actually a significant amount of magnesium amd manganese substitution for the iron and so the formula should be written as it is above
Ankerite Ca(Fe2+ 3 2 - Handbook of Mineralogy Occurrence: Formed in low-grade metamorphosed ironstones and sedimentary banded iron formations; in carbonatites; authigenic, diagenetic, or the product of hydrothermal alteration of carbonate sediments and in hydrothermal sulfide veins Siderite, dolomite

Ankerite - Natural Atlas Ankerite is a calcium, iron, magnesium, manganese carbonate mineral of the group of rhombohedral carbonates with formula: Ca (Fe,Mg,Mn) (CO3)2 In composition it is closely related to dolomite, but differs from this in having magnesium replaced by varying amounts of iron (II) and manganese
Ankerite - Oxford Reference It is a form of ferroan dolomite where ferrous iron substitutes for Mg in a solid solution series from dolomite (CaMg(CO 3) 2) to ankerite ((CaMg 0 75 Fe 0 25)(CO 3) 2) Ankerite often forms as a cement by diagenetic reaction (see diagenesis) from ferroan calcite at burial depths of about 2 5 km
