Preliminary results of Mössbauer room temperature measurements of Pultusk meteorite performed in standard and high resolution
Languages of publication
Abstracts
The results of two independent Mössbauer measurements of the same sample of the Pultusk meteorite are discussed. The measurements were performed at room temperature in standard conditions (256 channels) and with higher resolution (1024 channels). Very small differences in the percentage of the spectral areas of all mineralogical phases present in Mössbauer spectrum (olivine, pyroxene, metallic phases, troilite and ferric iron) convince that the measurement performed at standard conditions (256 channels) are sufficient for correct determination of the mineralogical composition of the investigated sample.
