Hematite is a canted antiferromagnet with reddish color that occurs widely on Earth and
Mars. Identification and quantification of hematite is conveniently achieved through its …

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 …

This paper provides an overview of the Curiosity rover's exploration at Vera Rubin ridge
(VRR) and summarizes the science results. VRR is a distinct geomorphic feature on lower …

The Sheepbed member of the Yellowknife Bay formation in Gale crater contains millimeter‐
scale nodules that represent an array of morphologies unlike those previously observed in …

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 …

Spherical Fe-oxide concretions on Earth, especially in Utah, USA, have been investigated
as an analog of hematite spherules found in Meridiani Planum on Mars to support …

Ferruginous deposits are iron-rich sediments or sedimentary rocks found in various sizes,
shapes, and compositions within sedimentary strata in different depositional settings. This …

Carbonate concretions are common features of sedimentary rocks of all geological ages.
They are most obvious in sandstones and mudstones as ovoid bodies of rock that protrude …

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 …
