Abstract

Study of four Chelyabinsk LL5 ordinary chondrite fragments with different lithology was carried out using optical and scanning electron microscopy, X-ray diffraction and 57Fe Mössbauer spectroscopy with a high velocity resolution at 295 K. Components revealed from the Mössbauer spectra were related to the main iron-bearing crystals of minerals such as olivine, pyroxene, troilite, kamacite, taenite and chromite. However, the relative amount of these minerals appeared to be different in the studied fragments.
