Malachite on Chalcopyrite Specimen - Natural Mineral Formation #3801063 (License: Personal Use)

This specimen features a matrix of chalcopyrite (CuFeS₂), partially altered to bright green malachite (Cu₂CO₃(OH)₂) through supergene processes. The surface displays pitted textures, botryoidal growths, and remnants of metallic luster, indicating exposure to oxidizing conditions near the surface. Such formations are commonly found in copper-rich hydrothermal veins.

Used on mineralogy websites, museum digital collections, or educational geology pages; targets collectors, students, and hobbyists seeking high-quality reference images of secondary copper minerals.
