The portion of Volcanic Lava Flow visible in this NASA - Mars Odyssey Orbiter's image is probably formed by one single Layer only. In fact, the visible Surface Texture appears to be made of Blocks of Lava which, after cooling, still moved (actually they "floated") on a real river of Molten Lava that was flowing underneath them. This particular phenomenon is (most likely) the cause of the "plate-like" texture which characterizes this entire portion of Martian Surface visible in this really fascinating frame.

This frame has been colorized in Absolute Natural Colors by (such as the colors that a human eye would actually perceive if someone were onboard the 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.
