Abstract: Selected minerals from oval inclusions (nodules) in the Morasko IAB iron meteorite have been investigated by electron microprobe (EMP) and micro-Raman spectroscopy. Collected spectra of quartz, forsterite-rich olivine, chromite, kosmochlor (Na–Cr-rich clinopyroxene) and Na-feldspar (albite) were compared with corresponding measurements of earth minerals and used for fast identification of meteorite fragments not EMP characterized. Some structural conclusions concerning particular minerals, like solid-state form or average crystallite size, were also drawn from the measured spectra.
