What is Artroeite?

Artroeite is a rare mineral that has fascinated geologists and collectors alike. Its unique properties and limited availability make it a subject of interest. Here are some intriguing facts about this mineral.

Artroeite is a rare mineral composed of lead, copper, and arsenate. Its chemical formula is PbAl₆(AsO₄)₂(OH)₁₆·4H₂O.
This mineral was first discovered in 1982 in the Tsumeb Mine, Namibia, a site known for its diverse and unique mineral specimens.
Artroeite typically forms in oxidized zones of lead-copper deposits, where it crystallizes in the triclinic system.
The mineral is named after Arthur Roe, an American mineralogist who made significant contributions to the field.
Artroeite crystals are usually small, often less than 1 millimeter in size, making them challenging to study and collect.

Physical Properties of Artroeite

Understanding the physical properties of Artroeite can help in identifying and appreciating this rare mineral. Here are some key characteristics.

Artroeite has a white to pale blue color, which can sometimes appear translucent.
The mineral has a vitreous to pearly luster, giving it a shiny appearance when light reflects off its surface.
It has a Mohs hardness of 2.5 to 3, making it relatively soft compared to other minerals.
Artroeite exhibits perfect cleavage in one direction, meaning it can easily split along a specific plane.
The specific gravity of Artroeite ranges from 2.8 to 3.0, indicating it is denser than many common minerals.

Chemical Composition and Structure

The chemical makeup and structure of Artroeite contribute to its unique properties. Let's delve into some fascinating details.
