Description

Malachite is a distinctive bright green mineral, often found in botryoidal or massive forms with characteristic concentric banding. Its vibrant color makes it easily recognizable.

Geological Context

Malachite is a secondary copper mineral that forms in the oxidation zones of copper deposits, typically in limestone environments where it precipitates from copper-bearing solutions.
