Description
Fougèrite mineral responsible for the bluish-green shade of gleysols in aquifers was identified as FeII − III oxyhydroxycarbonate, [Fe6(1-x)II Fe6xIII O12H2(7 − 3x)]2 + · [CO32- · 3H2O]2 − where the average ferric molar fraction x = [FeIII/Fetotal] was restricted to the [1/3–2/3] range, up till now. In this paper, Mössbauer spectra of gleys extracted from the schorre of maritime marshes have values of x in the [2/3–1] range. Magnetic properties of homologous chemical compounds studied by Mössbauer spectroscopy are explained with long range order of FeIII ions within Fe cation layers for x = 1/3, 2/3 and 1. Observed values are mixtures of topotactic domains that are in fact minerals with names proposed to IMA: fougèrite for x = 1/3, trébeurdenite for x = 2/3 and mössbauerite for x = 1.
