Scientific paper

FEM is here used to investigate the relaxation of impact craters on Mars, due to creep deformation of subsurface ice, that has been hypothesized as a basis for the 'terrain softening' type of landform degradation. A non-Newtonian viscoelastic rheology derived from experiments on frozen solids is asummed. The results thus obtained imply a Martian midlatitude softened terrain morphology consistent with relaxation in a deforming layer that is no more than 1 km in depth. The total amount of Martian subsurface ice is estimated on this basis.
