X-ray diffraction and Mössbauer spectroscopy of impactite from Jänisjärvi astrobleme

Abstract

X-ray diffraction and Mössbauer spectroscopy with optical microscopy, electron probe microanalysis and Raman spectroscopy were used for the study of Jänisjärvi impactite. The phase composition of impactite was determined and Mössbauer parameters of spectral components were estimated and related to the corresponding iron-bearing phases.
