Microbial life permeates Earth's critical zone and has likely inhabited nearly all our planet's
surface and near subsurface since before the beginning of the sedimentary rock record …

Paleosols are unrivaled terrestrial archives of paleoclimatic, paleoecological, and
paleoenvironmental conditions, yet their full utility and potential for unlocking critical …

Concretions are prevalent features in the generally lacustrine deposits of the Murray
formation in Gale crater. In this work, we document the morphologic, textural, and chemical …

Abstract The Mars Science Laboratory Curiosity rover has encountered both ancient lithified
and modern active aeolian dune deposits within Gale crater, providing an opportunity to …

Abstract Images from the Mars Science Laboratory (MSL) mission of lacustrine sedimentary
rocks of Vera Rubin ridge on “Mt. Sharp” in Gale crater, Mars, have shown stark color …

Aeolian processes have shaped and contributed to the geological record in Gale crater,
Mars, long after the fluviolacustrine system existed∼ 3 Ga ago. Understanding these …

The Curiosity rover on the Mars Science Laboratory mission has found extensive evidence
that Gale crater once hosted a habitable lacustrine environment; however, there are …

Biogenic mineral assemblages that form from circumneutral microbial reduction of iron in
smectite have been suggested as biosignatures in the geological record. However …

Carbonate concretion is an authigenic aggregation of minerals commonly found in
sandstone and shale, especially in organic-rich shale. In the outcrop, large number of …

Abstract The Mars 2020 Perseverance Rover imaged diagenetic textural features in four
separate sedimentary units in its exploration of the 25‐m‐thick Shenandoah formation at …
