초록

Fe compounds in scoria as distributed in the south-western area of Jeju Island were investigatedusing X-ray fluorescence spectroscopy, X-ray diffractometry, and 57Fe Mössbauer spectroscopy. The sampleswere prepared from four parasite volcanoes. It was found that these samples are typical basalt comprised ofSiO2, Al2O3, Fe, and silicate minerals. The Mössbauer spectra showed doublets for olivine, pyroxene, andilmenite as well as sextets for hematite and magnetite. The valence state of Fe is chiefly a 3+ charge statewith a slight 2+ charge state. It is expected that these results will add to the body of information related tothe formation mechanisms of Jeju Island.
