Protasite
Protasite is a rare uranium-bearing mineral with the chemical formula barium uranyl oxide hydroxide trihydrate. It belongs to the Strunz classification 4.GB.10 and is a member of the uranate group. This mineral is characterized by its monoclinic crystal system and typically exhibits a yellow to greenish-yellow color. Protasite has a dull to earthy luster, a relatively low hardness of approximately 2 to 2.5 on the Mohs scale, and a low to moderate density. It is commonly found in secondary uranium deposits and is notable for its hydrous nature and radioactive properties.

Overview
Protasite is a rare uranium-bearing mineral with the chemical formula barium uranyl oxide hydroxide trihydrate. It belongs to the Strunz classification 4.GB.10 and is a member of the uranate group. This mineral is characterized by its monoclinic crystal system and typically exhibits a yellow to greenish-yellow color. Protasite has a dull to earthy luster, a relatively low hardness of approximately 2 to 2.5 on the Mohs scale, and a low to moderate density. It is commonly found in secondary uranium deposits and is notable for its hydrous nature and radioactive properties.
Geological genesis
Protasite forms through the alteration of primary uranium minerals in oxidizing environments. It is typically associated with the weathering and oxidation of uranium-rich ores, where it precipitates from uranium-bearing solutions.
How to recognize it
Protasite can be identified by its low hardness, which is typically 2 to 2.5 on the Mohs scale, and its yellow to greenish-yellow color. It has a dull to earthy luster and a low to moderate density. The mineral can be distinguished from other uranium minerals by its specific chemical composition and hydrous nature. It is often confused with other uranyl hydroxides due to similar color and luster, but its low hardness and chemical analysis are key to accurate identification.
Host rocks
Protasite is typically found in secondary uranium deposits, often in association with oxidized uranium ores. It forms in weathered zones of uranium-rich environments, such as those found in uranium-bearing veins and altered igneous rocks.
Trivia
Protasite is notable for its hydrous composition, containing three water molecules per formula unit. It is a rare mineral, with few documented occurrences worldwide. Additionally, its uranium content makes it radioactive, which is a distinguishing feature for scientific study and mineralogical interest.
