“…Aeolian, fluvial, and lacustrine systems interact in a wide variety of settings on Earth (e.g., Al-Masrahy & Mountney, 2015;Slezak, & El-Baz, 1979). Drying lakes can provide a source of sediment that can be incorporated into bedforms (as at the White Sands Dune Field in New Mexico; McKee & Moiola, 1975) and ionrich waters from such lakes can provide a near-surface water table and a simple path to cementation. Evidence of interactions between fluvio-lacustrine and aeolian systems are preserved in the geologic record on Earth in a large range of basinal settings and points in geologic time (e.g., Havholm et al, 2003;Scherer et al, 2007;Timmons et al, 2007).…”

“…The nearby and subjacent lake sediments and associated stream channels provide the simplest source for water that could have seeped into the aeolian sands and provided a means for cementation. Either periodic inundation of the dune field, or a slow, constant rise in the water table, as occurs at the White Sands Dune Field in New Mexico (Baitis et al, 2014;Kocurek et al, 2007;McKee & Moiola, 1975), could cause the dune strata preservation. Preserved lee faces would be expressed as nested strata separated by bounding surfaces and 10.1029/2019JE006226…”

Ancient Stratigraphy Preserving a Wet‐to‐Dry, Fluvio‐Lacustrine to Aeolian Transition Near Barth Crater, Arabia Terra, Mars

Ancient lacustrine and aeolian sediments have been separately identified in a variety of locations on Mars. In this work, we interpret the depositional history of Barth crater and its surrounding area in Arabia Terra where exposed geologic units preserve a record of lacustrine and aeolian interaction. Aeolian sandstone in the study area overlies lacustrine strata and is interbedded with easily eroded interdune deposits. The aeolian sandstone preserves dune strata with structures that indicate paleo‐sediment transport toward the northwest. The aeolian unit also preserves a transition up‐section from separated barchan dunes to continuous transverse dunes, capturing the development of the ancient dune field from sediment limited to sediment rich. Inverted fluvial channels provide evidence that water was delivered to the area at the same time the dune field was present, providing a simple mechanism, via wetting and cementation, for aeolian strata preservation. This example of wet‐system aeolian accumulation preserves an upward drying sequence in the sedimentary record that may have been coincident with the widely hypothesized global climate transition. The terrains described in this work provide a framework for interpreting similar aeolian units in elsewhere on Mars, even where cross‐strata cannot be easily resolved.
