HiRISE: Mixtures of sulfates in Melas Chasma

Many locations on Mars have sulfates, which are sedimentary rocks formed in water. Within Valles Marineris, the large canyon system that cuts across the planet, there are big and thick sequences of sulfates. In this image, layering within the light-toned … Continue reading
