Abstract:
The OMEGA/Mars Express hyperspectral imager identified hydrated sulfates
on light-toned layered terrains on Mars. Outcrops in Valles Marineris,
Margaritifer Sinus, and Terra Meridiani show evidence for kieserite,
gypsum, and polyhydrated sulfates. This identification has its basis in
vibrational absorptions between 1.3 and 2.5 micrometers. These minerals
constitute direct records of the past aqueous activity on Mars.
