Hydrated sulphate minerals, including kieserite (MgSO4·H2O), gypsum (CaSO4·2H2O), and bassanite (CaSO4·~0.5H2O), have been detected on Mars (Gendrin et al., 2005; Wray et al., 2010), and polyhydrated ...
Interaction of Synthetic Sulphate “Green Rust” with Phosphate and the Crystallization of Vivianite
Anion Exchange Fe(II)FeIII-hydroxides Green Rust Layered Hydroxides Phosphate Vivianite
