Aurorae Chaos

Aurorae Chaos is a region of chaos terrain on Mars at the eastern end of the outflow channels from Valles Marineris into Chryse Planitia, centered at approximately ~324°E, 9°S. It is in the Margaritifer Sinus quadrangle.

Many layers are visible in the walls of Aurorae Chaos. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars.
