ankerite's Usage Examples:

metamorphic rocks; and with grunerite, magnetite, hematite, stilpnomelane, ankerite, siderite, calcite, chalcedonic quartz in iron formations.

It forms a series with dolomite, and with ankerite.

Solid solution exists between dolomite, the iron-dominant ankerite and the manganese-dominant kutnohorite.

rutile and ilmenite, and variants of glimmerite bearing graphite, spinel, ankerite, pyrite, apatite, and the carbonate minerals calcite and dolomite have.

These released elements form authigenic quartz, chert, calcite, dolomite, ankerite, hematite and albite, all trace to minor (except quartz) minerals found.

permeated the Great Limestone which, throughout its full thickness, was mineralised, producing siderite and ankerite minerals which were subsequently oxidised.

Uncommon sources of lime include coral, sea shells, calcite and ankerite.

mineralised, producing siderite and ankerite minerals which were subsequently oxidised, yielding a limonitic ore with an iron content of over 40 percent.
