Meteorite «Chelyabinsk»: mineralogical and petrographic characteristics

It is established that the meteorite Chelyabinsk LL refers to a group of low-iron olivine ordinary chondrites. The mineral composition of the meteorite is defined moderate-ferrous olivine (Fa24-36), iron-magnesium and calcium pyroxene, anorthoclase, high-chromium Cr-spinels, monosulfide series geksapirrotin-troilite-makkinavit, pentlandite, samorodnometallicheskimi phases (nickel-iron, iron-nikelil, copper), apatite, dolomite hibbingitom. In thermogenic rims installed presumably enstatite glass with inclusions of magnetite. Content was determined in the debris of the meteorite and its carbon isotopic composition.
