Layered Region in Gale Crater (EDM - Natural Colors; credits: Lunexit)

This EDM shows several Light-Toned Layers.
The origin of the sediments composing the Layers is unknown and could have included deposition in an ancient flood or lake or the deposition of windblown particles such as Dust or Volcanic Ash.
The relatively uniform character of the Layers and the manner of erosion suggests that the sediments are fine-grained.
