AB A number of tectonic structures have been located at the Thaumasia Plateau, Daedalia Planum and Aonia Terra, Mars. They include isolatedfolds with axial traces up to 200 km long, trains of tightly folded structures tens of km long, and thrusts. Their size and geometry are similar tothose on Earth, and the direction of compression seems to have varied amply with time, suggesting a complex tectonic evolution. Crater countson the deformed terrain point to Noachian to Early Hesperian ages. On the basis of the geometry and geological relations of these structures, wepropose that they form part of an old martian orogen, the Thaumasia–Aonia Orogen, which embraced not only the Thaumasia Plateau, but areasof Daedalia Planum, Aonia Terra and Nereidum Montes as well. A regional coherent layering is previous to the deformation and could representthe trace of even older stresses on the martian lithosphere.
