57Fe Mossbauer spectroscopy was used for studying the oxidation- and coordination-state of iron in chrysotile asbestos from various mining regions in Canada, Rhodesia, USSR and Yugoslavia. It was found that both the Fe2+ and Fe3+ ions occupy only the octahedral positions in the chrysotile crystal structure and that the Fe2+/Fe3+ ratio depends strongly on the mining region. Mossbauer spectra showed that the samples also contain magnetite. -P.Br.
