OMEGA detection map of hydrated or aqueous minerals. Map resolution is 500 m/pixel at equator, using OMEGA data with native resolution ranging 300 m/pix to ~4 km/pix. The color-composite map color-codes for aqueous mineralogy according to "spectral-mineral" classes defined in the source paper. Maps of individual spectral-mineral layer are also available. Red correspond to Fe/Mg phyllosilicates, Green to poly-hydrated or hyroxilated sulfate salts (or occasionnaly zeolites), Blue corresponds to mono-hydrated sulfate salts, Orange corresponds to carbonates (or occasionnaly serpentine), Cyan corresponds to Aluminosilicates (Al phyllosilicates) or hydrated (opaline) silica.
