Mineral Specimen #5300 Chalcopyrite and Hematite on Barite with Calcite
Pea Ridge Mine, Sullivan, Washington Co., Missouri
A cluster of large Barite crystals which are coated with golden colored Chalcopyrite crystals. Where the Barite is not covered with Chalcopyrite, the crystals have a reddish color due to the presence of a coating of micro Hematite crystals. The Chalcopyrite crystals are well formed, many with triangular faces, striations and some twinning. There is a gray colored Calcite perched on one side of the specimen.
Condition: Fairly Good
Flaws: There is breakage along the edges of most of the Barite crystals. The Calcite is bruised.
