Pseudomalachite - Wikipedia
Pseudomalachite is a phosphate of copper with hydroxyl, named from the Greek for "false" and "malachite", because of its similarity in appearance to the carbonate mineral malachite, Cu 2 (CO 3) (OH) 2. Both are green coloured secondary minerals found in oxidised zones of copper deposits, often associated with each other.
Pseudomalachite: Mineral information, data and localities.
From the Greek ψευδής for "false" for its similarity to, but not being, malachite. A secondary mineral found in oxidized zones of copper deposits. The phosphate analogue of Cornwallite. The monoclinic polymorph of Ludjibaite; a monoclinic variant polymorph of Reichenbachite. More common than both polymorphs.
Pseudomalachite – Mineral Properties, Photos and Occurrence
2021年4月16日 · Pseudomalachite is a common dark green secondary copper mineral, forming nice botryoidal or drusy specimens. Its popular among mineral collectors and usually occurs together with many other copper minerals. Pseudomalachite is a hydrated copper phosphate Cu 5 (PO 4) 2 (OH) 4 which crystallizes in the monoclinic crystal system.

PSEUDOMALACHITE (Copper Phosphate Hydroxide)
Chemistry: Cu 5 (PO 4) 2 (OH) 4, Copper Phosphate Hydroxide. Uses: as a very minor ore of copper and as mineral specimens. Pseudomalachite, as its name implies, is not malachite, but rather false malachite. It is not related to malachite at all, being a phosphate mineral while malachite is a carbonate.

Pseudomalachite from Virneberg mine The Pseudomalachite from Rheinbreitbach shows a worldwide unique diversity of habit. The mine was the first wehere isolated Pseudomalachite crystals were found. They reached a size of up to 5 mm which still can be considered to be the largest of the species worldwide today.
