Urancalcarite
Urancalcarite is a rare hydrated calcium uranyl carbonate hydroxide mineral with the chemical formula Ca(UO2)3(CO3)(OH)6·3H2O. It belongs to the orthorhombic crystal system and is classified under the Strunz system as 5.EA.10 and the Dana system as 16b.5.2.1. This mineral is part of the uranyl carbonate group, which is characterized by the presence of the uranyl ion (UO2^2+). Urancalcarite typically exhibits a vitreous luster, a dull white to pale green color, and a relatively low hardness on the Mohs scale. It has a moderate density and is generally found in uranium-rich environments.

Overview
Urancalcarite is a rare hydrated calcium uranyl carbonate hydroxide mineral with the chemical formula Ca(UO2)3(CO3)(OH)6·3H2O. It belongs to the orthorhombic crystal system and is classified under the Strunz system as 5.EA.10 and the Dana system as 16b.5.2.1. This mineral is part of the uranyl carbonate group, which is characterized by the presence of the uranyl ion (UO2^2+). Urancalcarite typically exhibits a vitreous luster, a dull white to pale green color, and a relatively low hardness on the Mohs scale. It has a moderate density and is generally found in uranium-rich environments.
Etymology
The name 'urancalcarite' is derived from its chemical composition, reflecting the presence of uranium and carbonate in its structure.
How to recognize it
Urancalcarite can be identified by its low hardness, typically around 2 to 3 on the Mohs scale, and its dull white to pale green color. It has a vitreous luster and a moderate density. The streak is white, and it is often distinguished from other uranium minerals by its specific chemical composition and crystal system. It is not commonly confused with other species due to its rarity and distinct properties.
Trivia
Urancalcarite is notable for its unique chemical composition, which includes the uranyl ion, a characteristic feature of uranium-bearing minerals. It is a rare mineral, with only a few known occurrences worldwide. Its orthorhombic crystal system is relatively uncommon among uranyl carbonates, making it an interesting subject for mineralogical study.
