HEDENBERGITE

Hedenbergite is a green or black coloured rock-forming mineral found in contact metamorphic rocks such as skarn, and also in certain igneous rocks and ore bodies. Hedenbergite was named by the Swedish chemist Johan Berzelius after his colleague Ludvig Hedenberg. Hedenbergite is a pyroxene containing iron and calcium. Crystals are rare, but those which do occur appear in short prisms with square cross-sections.
