Mysterious sulphate mountains in Juventae Chasma

The water that once flowed across Mars in its early days has left many traces. Among these, two terraced mountains located in the Juventae Chasma basin stand out; they appear to be composed of sediment layers. Spacecraft overflights have revealed that these are sulphate deposits containing minerals such as gypsum, alabaster or kieserite, which usually require water to form.
