Abstract

A. have investigated two groups of water ice-related Martian slope landforms in eight study areas. The periglacial debris aprons of mid-latitudinal regions developed in the last few hundred million years, as a result of the slow downslope movement and plastic deformation of rockice mixtures with cemented inner structure. Nowadays these are inactive or fossil landforms, indicating different climatic conditions in the past. The dark slope streaks on the dune fields of the sub-polar regions are the surface signatures of the pore volume-filling downslope seepage of liquid interfacial H2O, originating from the near-surface material in recent spring/summer periods. These two different types of ice-related slope landforms can be explained by the same process : partial melting of water ice in the shallow subsurface layers. Therefore, both can be considered as reliable locations and reachable sources of H2O reservoirs to be found on the planet. - (AM)
