View of the fracture system in the Utopia Planitia impact basin

This colour im­age was cre­at­ed from the nadir chan­nel ori­ent­ed per­pen­dic­u­lar to the sur­face of Mars and the colour chan­nels of the HRSC. It shows a net­work of huge frac­tures in Utopia Plani­tia. New re­search re­sults link the for­ma­tion of these huge ‘poly­gons’ in this re­gion to the pre­vi­ous ex­is­tence of an ocean in the Mar­tian North­ern Low­lands. Some of the graben show dark de­posits stretch­ing along their up­per edges. It is con­ceiv­able that these are dark, fine-grained ash lay­ers emerg­ing. They are the source of the widespread black sand dunes on Mars.

This colour image was created from the nadir channel oriented perpendicular to the surface of Mars and the colour channels of the HRSC. It shows a network of huge fractures in Utopia Planitia. New research results link the formation of these huge ‘polygons’ in this region to the previous existence of an ocean in the Martian Northern Lowlands. Some of the graben show dark deposits stretching along their upper edges. It is conceivable that these are dark, fine-grained ash layers emerging. They are the source of the widespread black sand dunes on Mars.
