Chalcopyrite with Peacock Ore – Norway

Specimens of chalcopyrite with peacock ore from Sulitjelma, Norway. Chalcopyrite is a well known copper iron sulphide mineral and also a major copper ore, it has a brassy yellow colour and a metallic lustre, however, overtime, this lustre can dulls as oxidation takes place. This mineral, like many other ore minerals forms through volcanogenic processes often being deposited as sulfide ore deposits, as such it can often be found in ore veins, although it can form by other processes too. These samples of chalcopyrite have slight inclusions of peacock ore and may also have minute inclusions of pyrite. These pieces would be a perfect addition to any mineral collection but may also be ideal for educational use, specimens are supplied a white card tray with an information label.
