Pie-like Mounds on Mars: A Comparative Morphometric Study of Features in Nepenthes/Amenthes and Chryse Planitia

Kurzfassung

Previous studies have shown that the Nepenthes/Amenthes region on Mars contains a large number of unusual kilometer-scale landforms—including cones, domes, and mounds—whose origins remain uncertain. Two main hypotheses have been proposed: one suggests these features are the result of subsurface sediment mobilization, potentially forming Martian analogs to terrestrial mud volcanoes, while the other attributes them to explosive volcanic activity involving magma–water interactions. This study aims to shed new light on this debate by analyzing the morphological and morphometric properties of these landforms.
