Abstract EN
A number of meteorites from the desert of Oman, classified as H-chondrites, with known and unknown ages, were studied by using 57Fe Mössbauer spectroscopy to determine their Fe3+-bearing compositions.
Mossbauer spectra measured at 78 K were composed of paramagnetic doublets superimposed on magnetic sextets.
the doublets are assigned to the silicate minerals olivine and pyroxene and Fe3+ phases.
the magnetic sextets in most samples showed the presence of at least three magnetic phases, namely troilite, magnetite and kamacite, which commonly exist in most ordinary chondrites.
the relative amounts (area %) of Fe3+ in the known-age meteorites, determined from the Mössbauer spectra, were plotted against their terrestrial ages.
the plot was used to estimate the terrestrial ages of meteorites with unknown terrestrial age.
