Abstract Mössbauer spectroscopy was applied to natural chromite samples from ophiolite complexes in the Philippines. Chemical and structural characterization of the chromite samples was also carried out using X-ray absorption fine structure (XAFS), X-ray diffraction (XRD) and X-ray fluorescence spectrometry (XRF). The Mössbauer spectra of the samples consisted of quadrupole doublets ascribable to Fe3+ in octahedral site, Fe3+ in tetrahedral site, and Fe2+ in tetrahedral site. The relative percentage of Fe3+ and Fe2+ ions suggested that these Philippine samples were formed under relatively high oxygen fugacity.
