Overview

Uranospinite is a hydrated calcium uranyl arsenate mineral with the chemical formula Ca(UO2)2(AsO4)2·10H2O. It belongs to the tetragonal crystal system and is classified as a uranyl arsenate in the Strunz system (8.EB.05) and as a uranyl arsenate in the Dana system (40.2a.2.1). The mineral is typically yellow to greenish-yellow in color, with a vitreous to pearly luster. It has a relatively low hardness of 2 to 2.5 on the Mohs scale and a low density of approximately 2.9 g/cm³. Uranospinite is part of the uranyl mineral group, which includes compounds containing the uranyl ion (UO2²⁺).

Etymology

Uranospinite is named after uranium, a key element in its chemical composition. The name reflects the presence of uranium in the mineral structure, which is a defining characteristic of the species.

How to recognize it

Uranospinite can be identified by its low hardness of 2 to 2.5 on the Mohs scale, which makes it easily scratched by a fingernail. It typically exhibits a yellow to greenish-yellow color and a vitreous to pearly luster. The mineral has a low density and does not show a distinct streak. Due to its rarity and specific chemical composition, it is often confused with other uranyl minerals, but its low hardness and characteristic color help distinguish it.

Trivia

Uranospinite contains uranium, making it a radioactive mineral. It is a hydrated compound, with ten water molecules in its structure, which is unusual for a mineral with such a high uranium content. The mineral is also notable for its low hardness, being softer than most common minerals, despite its complex chemical composition.
