..., or genesis, for Martian sand has not been demonstrated. This knowledge gap was recently heightened by the discovery of widespread sand motion, implying breakdown of grains to sub-sand sizes. To address the question of sand genesis, we investigated the source(s) of sand in Aeolis Dorsa (AD), the westernmost...

...Robert E. Jacobsen; Devon M. Burr Abstract The Aeolis Dorsa region of Mars preserves many ancient and topographically inverted fluvial deposits, some of which represent analogs to pre-vegetated meandering fluvial deposits on Earth. The regional stratigraphy of the Aeolis Dorsa preserves a tradition...
