Diverse Deposits in Melas Chasma

This scene includes chaotic deposits with a wide range of colors . The deposits are distinctive with both unique colors and small-scale textures such as fracture patterns.

These are probably sedimentary rocks, transported and deposited in water or air. The original layers may have been jumbled in a landslide. Dark or reddish sand dunes cover some of the bedrock.
