Journal ArticleDOI
Ancient Martian aeolian processes and palaeomorphology reconstructed from the Stimson formation on the lower slope of Aeolis Mons, Gale crater, Mars
Steven G. Banham,Sanjeev Gupta,David M. Rubin,J. A. Watkins,Dawn Y. Sumner,Kenneth S. Edgett,John P. Grotzinger,Kevin W. Lewis,Lauren A. Edgar,Kathryn M. Stack-Morgan,Robert Barnes,James F. 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.
Journal ArticleDOI
Large wind ripples on Mars: A record of atmospheric evolution
Mathieu G.A. Lapotre,Ryan C. Ewing,Michael P. Lamb,Woodward W. Fischer,John P. Grotzinger,David M. Rubin,Kevin W. Lewis,M. J. Ballard,Mitch D. Day,Sanjeev Gupta,Steven G. Banham,Nathan T. Bridges,D. J. Des Marais,Abigail A. Fraeman,John A. Grant,Kenneth E. Herkenhoff,Douglas W. Ming,Michael A. Mischna,Melissa S. Rice,Dawn Y. Sumner,Ashwin R. Vasavada,R. A. Yingst +21 more
TL;DR: A reevaluation of the wind-deposited strata in the Burns formation identifies potential wind-drag ripple stratification formed under a thin atmosphere on Mars, and reveals a third stable wind-driven bedform, with meter-scale wavelengths.
Journal ArticleDOI
The root of branching river networks
TL;DR: It is shown that branching at the uppermost reaches of river networks is rooted in two coupled instabilities: first, valleys widen at the expense of their smaller neighbours, and second, side slopes of the widening valleys become susceptible to channel incision.
Journal ArticleDOI
Chemistry, mineralogy, and grain properties at Namib and High dunes, Bagnold dune field, Gale crater, Mars: A synthesis of Curiosity rover observations.

TL;DR: Patterns in major element chemistry and volatile release data indicate two distinctive volatile reservoirs in Martian soils: amorphous components in the sand‐sized fraction (represented by Bagnold) that are Si‐enriched, hydroxylated alteration products and/or H2O‐ or OH‐bearing impact or volcanic glasses.
Journal ArticleDOI
Sedimentary processes of the Bagnold Dunes: Implications for the eolian rock record of Mars
Ryan C. Ewing,Mathieu G.A. Lapotre,Kevin W. Lewis,Mackenzie Day,Nathaniel Stein,David M. Rubin,Ryan C. Sullivan,Steven G. Banham,Michael P. Lamb,Nathan T. Bridges,Sanjeev Gupta,Woodward W. Fischer +11 more
TL;DR: The composite observations of the modern sedimentary processes highlight that the Martian eolian rock record is likely different from its terrestrial counterpart because of the large ripples, which are expected to engender a unique scale of cross stratification.
