Outline of Final Research Achievements

X-ray photoabsorption spectroscopy (XAS) is a nondestructive analytical technique for characterizing and identifying trace elements in compositionally complex natural materials. Furthermore, the combination of XAS and X-ray fluorescence analysis (XRF) using a micro-focused X-ray beam allow determination of both the chemical state of environmentally important trace elements and their spatial distribution in biogenic carbonates. A series of XRF/XAS mapping analyses clarified that the spatial distributions of sulfur compounds in Margaritifera Laevis depends on their chemical forms. The present research demonstrates that speciation analysis contributes to a more precise understanding of trace elements in biogenic carbonates for paleoclimatology.
