“…Hydrous minerals on the surface of Mars and their spatial and temporal distributions can be used to deduce the formation and evolution history of martian sediments, which is indicative of the environmental changes on Mars (Bishop & Rampe, 2016;Fraeman et al, 2013). Based on the visible and near-infrared spectroscopy (VNIR) data collected by the Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité (OMEGA) onboard the European Space Agency's Mars Express mission and the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) onboard the Mars Reconnaissance Orbiter (MRO), NASA, the mineralogy of martian sediments at the global scale, including mainly the distribution of hydrous minerals such as clay minerals (Du et al, 2023;Poulet et al, 2005) and sulfates (Gendrin et al, 2005), have been documented, which indicates the presence of different aqueous geochemical environments such as surface runoff and subsurface hydrothermal systems (Ehlmann et al, 2011). In addition to these well-crystallized minerals, Mars orbital and in situ data show that poorly ordered (and even nearly amorphous) minerals are widely distributed on the martian surface, mainly including aluminosilicate nanominerals (e.g., allophane), amorphous silica (e.g., opal-A), and nanophase iron minerals (including all poorly ordered materials containing octahedral Fe 3+ , which can be any combination of superparamagnetic hematite, goethite, ferrihydrite, lepidocrocite, schwertmannite, akaganeite, and other Fe 3+ -rich phases) (Bish et al, 2013;Blake et al, 2013;Morris et al, 1989Morris et al, , 2004Smith et al, 2021;Vaniman et al, 2014).…”
