Abstract

Eight illites with an iron content between 0.8% and 8.4%, which X-ray diffraction indicated to be free from interference from other iron-bearing minerals, were studied by Mössbauer spectroscopy at room temperature and 4.2 K. The Fe3+ quadrupole splitting varied from 0.59 mm/s for the iron-rich illites (>5 wt.% Fe) to 0.73 mm/s for those poor in iron (≲wt.% Fe). A distinction of iron sites in the illites with cis- and trans-OH coordination was not possible. The products of firing one illite at temperatures up to 1300 ‡C were also studied and revealed the disappearance of Fe2+, the gradual dehydroxylation of illite, and characteristic features of the products formed at higher temperatures.
