Study of hyperfine interactions in carbonaceous chondrite Isheyevo (CH/CB) using M?ssbauer spectroscopy with high velocity resolution

摘要

The unique meteorite bencubbinite Isheyevo CH/CB which was recently found in Bashkortostan, Russia was studied using M?ssbauer spectroscopy with high velocity resolution. M?ssbauer hyperfine parameters of metal in Isheyevo CH/CB external and internal regions demonstrated the presence of three phases such as martensite $upalpha _{2}$ -Fe(Ni,Co), kamacite $upalpha $ -Fe(Ni,Co) and disordered taenite $upgamma $ -Fe(Ni,Co).
