Abstract

Samples of titanomagnetite extracted from the ejecta of volcanoes in Iceland have been separated according to the intensity of their magnetisation and analysed with Mossbauer spectroscopy and electron microprobe analysis. It is shown that the magnetic peaks in the Mossbauer spectra vary widely between different source volcanoes and magnetic fractions, and thus that the Mossbauer spectrum of the titanomagnetite could be a useful fingerprint of the tephra.
