..., temperatures and [Fe]/[K] ratios. Thermal and chemical analyses are consistent with a model for non-stoichiometry in which domains of stoichiometric jarosite are intergrown with butlerite-like iron-deficient domains with a composition [Fe 2 (SO 4 ) 2 (OH) 2 (H 2 O) 4 ]. It was found that heterogeneous...
