arstivisiite

Arstivisiite is a rare, naturally occurring mineral discovered in 2010. It was first identified in the Khibina massif, located in the Kola Peninsula of Russia. The mineral is named after its chemical composition, which includes arsenic, titanium, and silicon. Its chemical formula is (AsO4)2TiO2(SiO4)2H2O.

Arstivisiite crystallizes in the monoclinic system and typically forms small, prismatic crystals. It is usually found in association with other minerals such as aegirine, microcline, and natrolite. The mineral has a pale yellow to colorless appearance and exhibits a vitreous luster.

Arstivisiite is of interest to mineralogists and geologists due to its unique chemical composition and the specific geological conditions under which it forms. Its rarity and the challenging conditions required for its formation make it a subject of ongoing study. Despite its scientific significance, arstivisiite is not known to have any practical applications or uses.
