Poldervaartite
Poldervaartite is a rare calcium silicate hydroxide mineral with the chemical formula CaCa[SiO3(OH)](OH). It belongs to the inosilicate group in the Strunz classification (9.AF.90) and the Dana classification (78.1.8.1). This mineral forms in a monoclinic crystal system and is typically found in a fibrous or radiating aggregate form. It exhibits a vitreous luster, a white to pale gray color, and a relatively low hardness of around 3 to 4 on the Mohs scale. Its density is moderate, and it is generally translucent to opaque. Poldervaartite is a hydrous mineral, containing hydroxide ions in its structure, and is notable for its unique composition and rarity in the mineral world.
