Hematite coating Dolomite after Calcite

Calcite and dolomite are two carbonate minerals, calcite contains primarily calcium while dolomite has both calcium and magnesium. Dolomite has less symmetry than calcite as a result of atomic ordering.

This specimen consists of scalenohedral crystals to 4 cm, originally formed in calcite, are now replaced by dolomite. This is a common pseudomorph in ore deposits. Specular hematite has covered the pseudomorphs, making for a very attractive specimen. From a classic locality. This specimen was part of the Charles Trantham (1936-2020) estate and comes with a Geologisch Centrum (Ootmarsum, Netherlands) label.
