Abstract Some H5 ordinary chondrite meteorites recovered from the desert region of Roosevelt County in New Mexico, USA and14C dated to determine the terrestrial age have been examined by57Fe Mössbauer spectroscopy. The preliminary results suggest the increasing oxidation of Fe0 in the iron-nickel alloy phase and of Fe2+ in the iron-sulphide and -silicate phases as a result of terrestrial weathering over ca. 38 000 years and which induces the formation of macroscopic iron oxide/oxyhydroxide phases.
