Abstract

Add info about the mineral composition of the Kunashak meteorite that fell in the Chelyabinsk region in 1949. It was found that the cosmic substance is composed of olivine (chrysolite), orthopyroxene (bronzite), clinopyroxene (augite), plagioclase (albite), maskelynite, chromite, magnetite, wustite, ilmenite, metals iron and nickel (kamacite and taenite), sulphides (troilite and pentlandite), chlorapatite and merrillite. This augite, ilmenite, pentlandite and chlorapatite identified in the Kunashak meteorite for the first time. For all minerals presents data on the chemical composition. Himself meteorite is an ordinary chondrite stone and belongs to petrological type L5-L6.
