Bell,Mackenzie Day,Ryan C. Ewing,Mathieu G.A. Lapotre,Nathan Stein,Frances Rivera-Hernandez,Ashwin R. Vasavada +17 more
TL;DR: The authors reported the analysis of a distinct aeolian deposit preserved in Gale crater, Mars, and evaluated its palaeomorphology, the processes responsible for its deposition, and its implications for Gale crater geological history and regional palaeoclimate.

TL;DR: The results suggest that dioctahedral smectite formed via near-surface chemical weathering driven by fluctuations in lake level and atmospheric infiltration, a process leading to the redistribution of nutrients and potentially influencing the cycling of gases that help regulate climate.
