- 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.
The redefinition of the name means the majority of old specimens labelled "ankerite" are now considered to be ferroan dolomite, and true ankerite is quite rare
- Ankerite – Mineral Properties, Photos and Occurrence
Ankerite is interesting and surprisingly uncommon carbonate, mostly limited to metasomatic rocks and hydrothermal veins It can form outstanding crystals and clusters Ankerite is a calcium-iron carbonate with ideal chemical formula CaFe (CO 3) 2
- Ankerite Mineral Data
Named after the Styrian (Austrian) mineralogist, Mathias Joseph Anker (1771-1843) Comments: White, rhombohedral crystals of ankerite and dark gray, metallic sphalerite on beige dickite Location: Prego mine, Kladno, Czech Rebublic Scale: Picture size 2 cm
- Ankerite Ca(Fe2+, Mg, Mn2+)(CO3)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 - an overview | ScienceDirect Topics
Dolomite, ankerite, siderite and quartz (chert) are the dominant gangue minerals, and important alteration minerals in most SEDEX deposits However, the extent and intensity of alteration are typically much less than in VMS deposits, reflecting the lower temperatures and higher pH of the fluids

Discover its properties, origins, and widespread applications in geology and industry Ankerite is a calcium, iron, magnesium, and manganese carbonate mineral with the chemical formula Ca (Fe,Mg,Mn (CO₃)₂ It is part of the larger group of carbonates and is closely related to siderite and dolomite
- Ankerite - Encyclopedia
Ankerite is a common carbonate of iron and calcium which forms a series with dolomite It is a fairly common matrix mineral in medium and low temperature hydrothermal veins, associated with dolomite, calcite, siderite and various sulphides
