Land of stucco and lava-filled cracks
Cool image time! The picture on the right, cropped and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter in December 2018 and released earlier this year. It shows a filled fault/fissure in a region dubbed Cereberus Palus, located south of the giant volcano Elysium Mons and to the west of Olympus Mons. This region is also biggest and most extensive sections of the transition zone between Mars’s southern highlands and the northern lowlands. This area however is so far from the lowlands its geology is more likely influenced more by the volcanism that created Elysium Mons to the north.
The overview map to the right illustrates this geography, with the black square indicating the location of this image.
The image itself strengthens my uneducated conclusion. This region of Cereberus Palus is filled with many faults, cracks caused as the terrain was stretched by the rising volcano. In some cases, as shown here, the cracks became filled with lava from below, as indicated by the lighter color of the material in those filled cracks..
What struck me most about this image was the terrain on the picture’s right. Looks exactly like the stucco on the outside of my house. It is as if a plasterer came by before the lava solidified and ran his putty knife over the surface to create the multiple small ridges.
It is worthwhile checking out the full resolution image. The details are especially intriguing.
