Study of visually different areas in the Chinga iron meteorite fragment using Mössbauer spectroscopy with a high velocity resolution

Abstract

Visually different areas on the saw-cut surface of Chinga metal meteorite fragment were observed. Study of metal samples from these areas was carried out using scanning electron microscopy, X-ray diffraction and Mössbauer spectroscopy with a high velocity resolution. The obtained differences in Mössbauer parameters may be related to the differences in the microstructural Fe-Ni phase composition. © 2012 Springer Science+Business Media Dordrecht.
