NASA Mars Picture of the Day: Polar Unconformity 08-27-2006
Mars Global Surveyor Mars Orbiter Camera
MGS MOC Release No. MOC2-1566, 26 August 2006
NASA/JPL/Malin Space Science Systems |
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows layered material exposed on a slope in the north polar region. An unconformity is visible in the middle/upper left of the image, where layers are abruptly truncated. Unconformities are indicators of drastic change in the region—the lower layers were deposited first, then eroded, then the upper layers were deposited. |
