Malachite

Cu2(CO3)(OH)2
Monoclinic heart IMA grandfathered

Malachite is a vivid green mineral with the chemical formula copper(II) carbonate hydroxide, Cu2(CO3)(OH)2. It crystallizes in the monoclinic system and is characterized by a Mohs hardness of 3.75, a density of 3.85 g/cm³, and a bright green streak. The mineral exhibits a waxy to silky luster and is typically found in shades of green, often with banded or mottled patterns. Malachite is classified as a carbonate mineral in the Strunz system (5.BA.10) and in the Dana system (16a.3.1.1). It is commonly used as an ornamental stone and has historical significance in pigments and jewelry.

Etymology

The name 'malachite' is derived from the Greek word for peafowl, due to the resemblance of its green color to the bird's plumage.

Geological genesis

Malachite is typically formed through the weathering of copper ores, often in the oxidation zones of copper sulfide deposits. It is commonly associated with other secondary copper minerals and forms in sedimentary and hydrothermal environments.
