Antofagastaite

Na2Ca(SO4)2·1.5H2O
heart IMA approved

Antofagastaite is a rare hydrated sodium calcium sulfate mineral with the chemical formula Na2Ca(SO4)2·1.5H2O. It belongs to the sulfate mineral class and crystallizes in the monoclinic crystal system. This mineral is typically colorless to white, with a vitreous luster. It has a relatively low hardness of approximately 2.5 to 3 on the Mohs scale and a specific gravity of around 2.0 to 2.2. Antofagastaite is notable for its soft, brittle nature and is not commonly found in mineral collections due to its rarity and instability under normal conditions.

Overview

Etymology

Antofagastaite is named after the Antofagasta Province in Chile, where it was first discovered. The mineral was approved by the International Mineralogical Association (IMA) as a valid species.

How to recognize it

Antofagastaite can be identified by its low hardness, typically 2.5 to 3 on the Mohs scale, and its colorless to white color. It has a vitreous luster and a low specific gravity. A streak test will yield a white streak. Due to its softness and rarity, it is easily confused with other soft sulfate minerals, but its chemical composition and crystal system help distinguish it.

Trivia

Antofagastaite is a rare mineral with a unique chemical composition that includes a half-molecule of water, making it chemically distinct from other sulfates. It is named after a specific geographic location, the Antofagasta Province, which is uncommon for many minerals. Its low hardness and instability under normal conditions make it a challenging mineral to study and preserve.
