Zincroselite
Zincroselite is a rare hydrated calcium zinc arsenate mineral with the chemical formula Ca2Zn(AsO4)2·2H2O. It belongs to the monoclinic crystal system and is classified in the Strunz category 8.CG.10 and the Dana classification 40.2.3.3. The mineral typically exhibits a vitreous luster and is usually white to pale pink in color. It has a relatively low hardness on the Mohs scale and a moderate density. Zincroselite is a member of the roselite group, which includes arsenate minerals with similar structural characteristics.

Overview
Zincroselite is a rare hydrated calcium zinc arsenate mineral with the chemical formula Ca2Zn(AsO4)2·2H2O. It belongs to the monoclinic crystal system and is classified in the Strunz category 8.CG.10 and the Dana classification 40.2.3.3. The mineral typically exhibits a vitreous luster and is usually white to pale pink in color. It has a relatively low hardness on the Mohs scale and a moderate density. Zincroselite is a member of the roselite group, which includes arsenate minerals with similar structural characteristics.
Etymology
Zincroselite is named after the mineral roselite, reflecting its structural and compositional similarities within the roselite group.
How to recognize it
Zincroselite can be identified by its monoclinic crystal system and vitreous luster. It has a low hardness, typically below 4 on the Mohs scale, and a moderate density. The mineral usually appears white to pale pink in color and may have a white streak. Due to its rarity and similarity to other arsenate minerals, it can be confused with members of the roselite group.
Trivia
Zincroselite is a rare mineral, known for its unique chemical composition as a hydrated calcium zinc arsenate. It belongs to the monoclinic crystal system, which is less common for arsenate minerals. Its name reflects its relationship to the roselite group, a family of structurally related minerals.
