Abstract

Study of metal grains extracted from ordinary chondrite Tsarev L5 using Mossbauer spectroscopy with high velocity resolution was made for the first time. Three magnetic and one paramagnetic components were revealed in Mossbauer spectrum of extracted metal. These components were related to correspondent phases of Fe–Ni–Co alloy while only two magnetic components related to metal were revealed in the spectrum of bulk meteorite sample. The results obtained were in agreement with metallographic study of metal grains in meteorite Tsarev L5 which demonstrated the presence of four Fe(Ni, Co) phases.
