Résumé

Numerous studies using orbital HiRISE and CTX data show evidence for extensive fan formation across the Martian surface [1, 2]. Fan-shaped deposits record a combination of fluvial, debris flow, and deltaic processes, with many fans likely forming during the late Hesperian or Amazonian [1, 3]. Curiosity-based observations of the deeply eroded deposits of the Gediz Vallis ridge (GVR), near the base of Aeolis Mons (Mt. Sharp), provide our first cross-sectional observation of a Martian fan, revealing episodic deposition by debris flows and reworking by fluvial processes.
