Mars Global Surveyor Mars Orbiter Camera

MGS MOC Release No. MOC2-1180, 11 August 2005

NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows severely tilted–dipping–layered rocks in Oudemans Crater in the Valles Marineris region of Mars. The rocks have a light tone and are somewhat broken-up by faults. These rocks were deposited in flat-lying layers. Sometime later, Oudemans Crater formed by meteor impact. When that occurred, rocks that were underneath the site of the impact were uplifted and tilted by the force of the impact. The light tone and repeated nature of some of the layers suggests that these may be sedimentary rocks.
