Geological structures in the Noctis Labyrinthus region
The Noctis Labyrinthus region, created by tectonic extension processes, is a very special area in the southern Martian highlands, which are very rich with exciting geological phenomena. In the text associated with the geological structures marked here – 'graben structures' are tectonic extension structures in which parts of the landscape have collapsed along fault lines; 'chaotic terrain' is a technical term for a landscape shaped by erosion processes in which rocks or bergs not yet fully weathered by erosion are arranged 'chaotically'; 'very large ripples' are long, high dune ridges 150 to 200 metres apart and arranged perpendicular to the wind direction; 'channel emerging …' shows a small river valley eroded by water on the valley floor; 'light toned materials' are bright deposits of hydrated minerals, that is minerals altered by contact with water; 'large landslide shows the remains of a landslide along an approximately 50-kilometre-long and three-kilometre-high escarpment.
