SUMMARY: The European Space Agency's Mars Express spacecraft took this unusual photograph of the Aureum Chaos region on Mars. It's located at the eastern part of the Valles Marineris, near a large impact crater called Aram Chaos. The history of this region is very complex. It was probably filled with sediment and then large areas collapsed due to the removal of ice, water or magma; various flat-topped mesas remained.

The funny thing about this picture is that I can't see it as a series of mesas, only a strange network of channels. I know this is an optical illusion, and I can see it properly in the black and white image.

Maby the surfice of mars in this region is like, oh i forgit the name of it :huh: . anyway it's a rock that disolves very fast in geological terms in water or something else liquid.

Limestone or sandstone possibly?

Somethings in the black & white image certainly are clearer than in the coloured one.

I saved it and flipped it 180 degrees with MS Photo Editor.
Looks like chasms now that the light seems to be coming from
overhead.

Mesas? Even in the B/W picture, following the shadows, it looked like depressions. It reminds me of dikes, magma filling fracture zones and during some uplift or erosive period the softer surrounding rock is eroded away exposing these linear, wall-like mountains. Since we are primarily witnessing wind erosion, one can find flat-bottomed valleys in the sand dunes between El Centro, California and Yuma, Arizona. Instead of mesas, table-topped hills and mountains, I'm seeing flat-bottomed depressions between dikes in an ancient fracture zone.

Oh, well....

Well Eric Vaxxine these rocks do dizolve in water but it's not the rock i am thinking of. It had a werd name. Thanks :)
