X-ray diffraction and M?ssbauer spectroscopy of Gandom Beryan 008 ordinary chondrite

摘要

The results of the study of newly found Gandom Beryan 008 H5 ordinary chondrite by means of X-ray diffraction and M?ssbauer spectroscopy with additional characterization by optical and scanning electron microscopy are considered. The main iron-bearing phases and their hyperfine parameters were determined. A comparison of Fe~(2+) occupancies of the M1 and M2 sites in olivine and orthopyroxene determined by X-ray diffraction and M?ssbauer spectroscopy data demonstrates some consistency and partial oxidation of Fe~(2+) in olivine.
