Zavaritskite is a rare mineral of the halide class, bismuth oxyhalide with the chemical formula (BiO)F. It is named after the Soviet geologist and petrographer, academician of the USSR Academy of Sciences Alexander Nikolaevich Zavaritsky. It was discovered in 1962 by Soviet scientists. Zavaritskite is part of matlockite group of minerals.
==Description== Zavaritskite is a gray mineral with a greasy or semi-metallic luster; opaque, only slightly translucent in very small grains. The mineral powder is finely dispersed, colorless. The crystallization process of zavaritskite occurs in a square system, due to which the mineral forms sufficiently fine-grained powder cryptocrystalline aggregates.
