Structural Analyses of the Martian Crust in a Variety of Tectonic Settings

image: Extensional faults on Mars create complex patterns on the surface and, based on research by SwRI scientists, can produce strings of depressions termed pit crater chains. Using SwRI-developed 3D-StressĀ® software on these faults allows analysis of the slip tendency and dilatant tendency of these faults.

image: Wrinkle ridges on Mars form in areas where the crust has been compressed. Analyses by SwRI scientists have revealed small-scale deformation within these wrinkle ridges that provide insight into the conditions under which these features formed.
