In this VIS image, taken by the NASA - Mars Odyssey Orbiter on August, 10th, 2014, and during its 56.139th orbit around the Red Planet, we can see - in particular on the upper portion of the frame - several different kinds of Flow Surfaces, including "Platy" (--->  a Rocky Terrain of Igneous Origin thatb has been split into thin and flat sheets of Rocks - often resembling to Strata - as a result of the occurrence of an uneven cooling of the Lava) and "Lobate" (---> Flows shaped like Lobes). All these ancient Lava Flows are part of the Volcanic Region known as Daedalia Planum.

As it usually occurs in the Volcanic Regions of Mars, only a small number (less than twenty, we think) of (relatively) recent Impact Craters can be seen over the photographed Area.

This image (which is an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18707) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
