Outline of Final Research Achievements

Isotope fractionation of various elements in various geochemical systems has been predicted by the speciation of these elements in the samples, which can provide new isotopic geochemical tool to clarify the history of the earth and planet. For example, tungsten isotope fractionation between its dissolved species and adsorbed species on iron and manganese oxides has been studied based on the speciation and isotope analyses. The 0.6 permil isotope fractionation observed in this system can be useful for the better understanding of redox history of the earth, especially when applied with molybdenum isotope which is sensitive only for the adsorption on manganese oxide. Similar isotope fractionation was predicted and actually observed for germanium and rubidium in the adsorption systems. Moreover, isotope fractionation of Fe at the 4 permil level was observed during the evaporation of Fe such as in anthropogenic combustion process, which can be useful to distinguish source of Fe in aerosols.
