Garnierite vs. Malachite — What's the Difference?

Garnierite is a general name for a green nickel ore which is found in pockets and veins within weathered and serpentinized ultramafic rocks. It forms by lateritic weathering of ultramafic rocks and occurs in many nickel laterite deposits in the world.

Malachite is a copper carbonate hydroxide mineral, with the formula Cu2CO3(OH)2. This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.

A pale green or apple-green mineral, (Ni, Mg)3Si2O5(OH)4, used as a gemstone and as an important nickel ore.

A light to dark green carbonate mineral, Cu2CO3(OH)2, used as a source of copper and for ornamental purposes.

(mineral) A green nickel ore found in fissures of weathered ultramafic rocks

(mineral) A bright green mineral, a basic copper carbonate, Cu₂CO₃(OH)₂; one of the principal ores of copper.

An amorphous mineral of apple-green color; a hydrous silicate of nickel and magnesia. It is an important ore of nickel.

A mild green colour, like that of the mineral.

A green mineral consisting of hydrated nickel magnesium silicate; a source of nickel

Of a colour ranging from olive-taupe to a mild to deeply-rich (at times seemingly translucent) green, like that of the mineral which is present on oxidized copper.

Native hydrous carbonate of copper, usually occurring in green mammillary masses with concentric fibrous structure.

A green mineral used as an ore of copper and for making ornamental objects
