Nicolas Mangold coauthored an analysis of Perseverance rover images of sedimentary outcrops in Jezero crater on Mars. Inclined layers support delta advance into a lake, while overlying coarse deposits indicate later energetic floods.[ref]
Perseverance rover reveals an ancient delta-lake system and flood deposits at Jezero crater, Mars by Nicolas Mangold and others. Abstract: rover outcrops, delta geometry and boulder-bearing flood deposits
The close views reveal structures that orbital images could not resolve. Their ordering reconstructs changing flow conditions, illustrating how sedimentology turns an exposed rock face into evidence about a past hydrological system.
