- Аннотация: —The bulk of the main part of the Chelyabinsk meteorite (ordinary chondrite, LL5) for the presence of nanometer pores therein is investigated by means of positron annihilation lifetime spectroscopy. In addition, its phase composition is studied with the help of transmission Mössbauer spectroscopy (MS). These results are refined by means of X-ray powder diffraction. The obtained data demonstrate an absence of nanometer pores in the meteorite. MS data show that the meteorite consists of mineral phases (olivine and pyroxene), which are rather typical of ordinary chondrites. Iron is present in sulfide and nickel forms. Possible applications of nuclear physics methods for analysis of the origin of meteorites and evolution of the Solar System are discussed.
