Turneaureite

Ca5(AsO4)3Cl
Hexagonal root IMA approved

Turneaureite is a rare phosphate mineral with the chemical formula calcium arsenate chloride, Ca5(AsO4)3Cl. It crystallizes in the hexagonal crystal system and is classified within the apatite group of minerals. This mineral is typically found in association with other calcium-rich and arsenic-bearing minerals. It has a relatively low hardness on the Mohs scale, a moderate density, and exhibits a vitreous luster. Its color is often white or pale in tone. Turneaureite is considered a nesosilicate, though it is more accurately described as an arsenate mineral due to the presence of arsenic in its structure.

Turneaureite is named after Frederick S. Turneaure, a Canadian mineralogist, in recognition of his contributions to the field of mineralogy.

How to recognize it

Turneaureite can be identified by its hexagonal crystal habit and its chemical composition. It has a hardness of approximately 4 to 5 on the Mohs scale, a white streak, and a vitreous luster. Its color is typically white or pale, and it can be distinguished from similar minerals by its arsenic content and chemical analysis.

Trivia
