Peacock Ore derives its name from its brilliant iridescent hues, which resemble the shimmering plumage of a peacock. This mineral is primarily composed of bornite (Cuâ‚…FeSâ‚„), but it is often confused with chalcopyrite (CuFeSâ‚‚) due to their similar appearance. While both minerals exhibit vibrant metallic colours, chalcopyrite tends to be more golden, while bornite displays deeper blues and purples after oxidation.
Alternate names for Peacock Ore include:
- Bornite (its official mineralogical name)
- Iridescent Ore (due to its rainbow-like surface)
- Purple Copper Ore (a reference to its dominant colouration)
- Chalcopyrite (often mistakenly identified as peacock ore, though it is a distinct mineral)
Composition and Physical Characteristics
Peacock Ore is a copper iron sulfide mineral that undergoes oxidation upon exposure to air, creating a striking tarnish of blues, purples, reds, and golds.
Physical Properties:
- Chemical Formula: Cuâ‚…FeSâ‚„ (Bornite)
- Hardness: 3.0 on the Mohs scale
- Lustre: Metallic
- Transparency: Opaque
- Fracture: Uneven to conchoidal
- Streak: Greyish-black
- Specific Gravity: 4.9 – 5.3
Varieties of Peacock Ore
Although bornite itself does not have formal varieties, the colouration of Peacock Ore varies depending on oxidation levels. Freshly mined bornite is generally bronze or brown, but after exposure to air and moisture, it develops its characteristic peacock-like hues.
Locations and Notable Finds
Peacock Ore is found worldwide in copper-rich deposits, often alongside other sulfide minerals such as chalcopyrite, pyrite, and sphalerite. Notable locations include:
- United States (Arizona, Montana, and Connecticut) – Some of the largest deposits of bornite are found here.
- Mexico – Produces vibrant specimens frequently used in jewellery.
- Peru – Known for high-quality Peacock Ore with strong iridescence.
- Canada (British Columbia, Ontario) – Major copper mining sites yield significant amounts of bornite.
- Australia – Found in several copper-rich mining regions.
- Namibia and Zambia – African sources known for deep-coloured specimens.
Archaeological and Significant Finds
- Copper ore deposits containing bornite have been mined since ancient times, particularly in Mesopotamia and Egypt, for their use in metalworking.
- In the 19th and 20th centuries, Peacock Ore was often mistaken for valuable ores and mined alongside copper for industrial applications.
- Historical artefacts made of copper-based alloys may contain traces of bornite due to its natural copper content.
Historical and Current Usage
