Abstract Sedimentary fans are key targets of exploration on Mars because they record the history surface aqueous activity and habitability. The sedimentary fan extending from Neretva Vallis breach Jezero crater's western rim is one 2020 Perseverance rover's main targets. spent ∼250 sols exploring collecting seven rock cores lower ∼25 m exposed within fan's eastern scarp, a sequence informally named “Shenandoah” formation. This study describes sedimentology stratigraphy Shenandoah formation...
Significance Significant debate exists whether the global population of Martian debris-covered glacier deposits formed continuously over past 300 to 800 Ma, or they during punctuated episodes ice accumulation obliquity maxima (lasting ∼10–100 ka). We show that, like ancient glaciers on Earth, boulder banding glacial indicates multiple and advance. In our analysis, periods are followed by removal from zone, forming debris bands. report a median five six glacial/interglacial transitions...
