Chalcopyrite – Morocco
Chalcopyrite mineral samples from Morocco, exhibiting typical yellow brassy colour with a metallic lustre. Lower grade when compared to our Norwegian stock but also includes occurrences of bornite which is a blue colour. Samples are available in 3 sizes, each supplied in a labelled card tray.
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 particular specimens of chalcopyrite come from Morocco and are a lower grade of material when compared to our Norwegian stock, yet they still show occurrences of bright brassy chalcopyrite within the host rock. The mineral its self is fairly soft, coming up at a hardness of 3.5 to 4 on the Mohs scale & a green tinged black streak when pulled across a streak plate, these pieces are available in 3 various sizes and will come supplied in a card tray with an information label.
