Light-Toned Deposits in Noctis Labyrinthus

CRISM observations of this region of the Noctis Labyrinthus formation have shown indications of iron-bearing sulfates and phyllosilicate (clay) minerals.

HiRISE observations have revealed exposed layers which are possibly the sources of the signatures seen by CRISM. In the subimage, the layering can be seen in the lower part of the image. To the upper left one can see a dune field which covers other beds.
