Historical & Geological Background:
Chalcopyrite is a copper iron sulfide mineral (CuFeS₂) and is one of the most important ores of copper worldwide. It typically forms in hydrothermal veins and massive sulfide deposits associated with igneous and metamorphic environments.

The mineral is known for its brassy yellow metallic lustre, which can tarnish to iridescent colours over time due to surface oxidation. Chalcopyrite has been mined for centuries as a primary source of copper, which has been essential in tools, alloys, and industrial applications throughout human history.
