The nontronite-saponite series: An experimental approach

open access: yesEuropean Journal of Mineralogy, 1994
The study of the octahedral Fe-Mg substitution in smectites was conducted using clay synthesis at 200°C. Mossbauer data revealed that only ferric iron occurs in synthesized smectites. The studied series is then obviously heterovalent. All synthesized clays were tetrahedrally charged leading to structural formulae varying between nontronite and saponite
