PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

PIA04140: Severely-Dipping Layers
NASA's Mars Global Surveyor shows severely tilted, or 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.

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.
