Mineralogy of a Mudstone at Yellowknife Bay, Gale Crater, Mars
TLDR
Sedimentary rocks at Yellowknife Bay (Gale crater) on Mars include mudstone sampled by the Curiosity rover, indicating that clay mineral formation on Mars extended beyond Noachian time.

X-ray Diffraction Results from Mars Science Laboratory: Mineralogy of Rocknest at Gale Crater
TLDR
The Mars Science Laboratory rover Curiosity scooped samples of soil from the Rocknest aeolian bedform in Gale crater that revealed plagioclase, forsteritic olivine, augite, and pigeonite, with minor K-feldspar, magnetite, quartz, anhydrite, hematite and ilmenite, which are similar to that found on Earth in places such as soils on the Mauna Kea volcano, Hawaii.

Mineralogy of an active eolian sediment from the Namib dune, Gale crater, Mars
The Mars Science Laboratory rover, Curiosity, is using a comprehensive scientific payload to explore rocks and soils in Gale crater, Mars. Recent investigations of the Bagnold Dune Field provided the…

Redox stratification of an ancient lake in Gale crater, Mars
TLDR
The results will aid the understanding of where and when Mars was once habitable and constrain the chemical environment within the lake in Gale crater, as well as short- and long-term climate variations in and around Gale crater.

Curiosity at Gale Crater, Mars: Characterization and Analysis of the Rocknest Sand Shadow
TLDR
The Rocknest aeolian deposit is similar to aeOLian features analyzed by the Mars Exploration Rovers Spirit and Opportunity and implies locally sourced, globally similar basaltic materials or globally and regionally sourced basALTic components deposited locally at all three locations.

Evolved gas analyses of sedimentary rocks and eolian sediment in Gale Crater, Mars: Results of the Curiosity rover's sample analysis at Mars instrument from Yellowknife Bay to the Namib Dune
The sample analysis at Mars instrument evolved gas analyzer (SAM‐EGA) has detected evolved water, H2, SO2, H2S, NO, CO2, CO, O2, and HCl from two eolian sediments and nine sedimentary rocks from Gale…

Mineralogy, provenance, and diagenesis of a potassic basaltic sandstone on Mars: CheMin X‐ray diffraction of the Windjana sample (Kimberley area, Gale Crater)
TLDR
The presence of sediment from many igneous sources, in concert with Curiosity's identifications of other igneous materials (e.g., mugearite), implies that the northern rim of Gale Crater exposes a diverse igneous complex, at least as diverse as that found in similar‐age terranes on Earth.

Surface clay formation during short-term warmer and wetter conditions on a largely cold ancient Mars
TLDR
A geochemical model for the state of early Mars suggests that short-term warm events grafted onto a generally cold climate could form Al-rich phyllosilicates in short-lived surface water bodies and Mg-rich ones in hydrothermal subsurface environments.
