Abstract: The identification of saponite and amorphous material in the Sheepbed mudstone of Gale Crater by CheMin XRD on Mars Science Laboratory [1] has highlighted the importance of understanding the nature of martian phyllosilicates and amorphous material, as they have the potential to reveal the fluid history of habitable terrains [2,3]. The nakhlite meteorites are the only martian samples on Earth which contain phyllosilicates and poorly crystalline or amorphous material [4-10], which we can study by new XRD and X-ray Absorption techniques and TEM to provide an accurate Fe3+/ΣFe ratio, composition and structural comparison to the in situ analyses on Mars.
