Ti K-edge XANES spectra of tektites and reference compounds. TiO2 anatase and moldavite-green have the highest peak around 4984.7 eV (position A) and the second peak around 5001.1 eV (position B). The peak height of position A is always weaker than those of position B in the other tektites in which Ti occupies five- and four-coordinated sites. |
