Morphological analyses of small and medium size landforms in Scandia Cavi and Olympia Undae, Northern circumpolar region of mars

<p>This article presents a systematic morphological analysis of the topographic <a href="https://www.sciencedirect.com/topics/earth-and-planetary-sciences/landform" target="_blank">landforms</a> at Olympia Undae and Scandia Cavi in the northern circumpolar region of Mars. The study has been performed using images from Mars Express and <a href="https://www.sciencedirect.com/topics/earth-and-planetary-sciences/mars-reconnaissance-orbiter" target="_blank">Mars Reconnaissance Orbiter</a>, as well as topographic profiles from <a href="https://www.sciencedirect.com/topics/earth-and-planetary-sciences/mars-global-surveyor" target="_blank">Mars Global Surveyor</a> of 200 small and medium-size geological landforms (16 ​km diameter on average). The main morphometric parameters of these landforms have allowed their classification into three groups that include cratered structures, non-cratered structures, and complex irregular structures. In the cratered group, three subgroups can be distinguished: cratered cones, impact craters and undifferentiated craters. In turn, the non-cratered group includes two subgroups: peaked domes and simple domes. Their possible relation to internal, surface and impact processes is discussed. </p>
