PSP_004423_1755_RED_abrowse-PCF-LXTT.jpgInverted Channels and Layers near Juventae Chasma (an Image-Mosaic in Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team:)98 visitePSP_004423_1755 shows Plains North of the South-Western Juventae Chasma, a Canyon belonging to the gigantic Valles Marineris Canyon System.

There are 3 distinct type of Terrains in this image:

1) Plains with possible Inverted Channels,
2) Plains with exposed Layers and
3) Layers on a wall of Juventae Chasma.

The right half of the image contains Plains with Craters and Sinuous Ridge Features that are possibly Inverted Stream Channels.
Inverted relief occurs when a formerly low-lying area becomes high-standing. There are several possible reasons why Channels might stand out in inverted relief. The streambed material may become cemented by precipating minerals, contain larger rocks, or become filled with lava, all which are more resistant to erosion.
Finer-grained, more erodable material surrounding the channel is blown away by the wind or carried away by water, leaving the resistant channel bed high and dry around its environs.

Another example of erosion can be seen in the next Terrain which covers about 2/3 of the left half of the image. Erosion has exposed a beautiful series of light and dark tone Layers (approximately 1 Km across). In the inset, the smallest of the rings is the deepest exposed Layer.

Layers are common in the Martian Canyons, but it is unknown what process formed them. It is likely, though, that the Layers in the Plains here are made of the same material as the Layers in the Canyons. 1 commentiMareKromium11/15/10 at 14:26walthari: spiegazione esaustiva e geologicamente ineccepibil...
