This HiRISE image shows faulted layered deposits in a part of Valles Marineris called Candor Chasma.
Often faults cut through the layered material in this area, indicating that the rocks underwent stress causing them to crack and shift in position after they were deposited.
This area also has a high abundance of hematite. Hematite is a mineral that can precipitate out of water, so its presence on Mars is of special interest for understanding the distant past.
