What is Malachite?
Malachite is a secondary mineral that forms in the oxidation zones of copper deposits. It typically develops as botryoidal, fibrous, or stalactitic masses, displaying characteristic concentric rings and deep green hues. The mineral derives its name from the Greek word malache, meaning “mallow,” due to its resemblance to the leaves of the mallow plant.
Malachite is commonly found alongside other copper minerals such as azurite, chrysocolla, and cuprite. It often occurs in both massive and crystalline forms, though the former is more prevalent. The distinctive green color of malachite results from its high copper content.
