ChemCam is a remote sensing instrument suite on board the “Curiosity” rover (NASA) that
uses Laser-Induced Breakdown Spectroscopy (LIBS) to provide the elemental composition …

Early Mars climate research has well-defined goals (MEPAG 2018). Achieving these goals
requires geologists and climate modelers to coordinate. Coordination is easier if results are …

The geological units on the floor of Jezero crater, Mars, are part of a wider regional
stratigraphy of olivine-rich rocks, which extends well beyond the crater. We investigated the …

The Mars Science Laboratory rover Curiosity scooped samples of soil from the Rocknest
aeolian bedform in Gale crater. Analysis of the soil with the Chemistry and Mineralogy …

Decades of speculation about a warmer, wetter Mars climate in the planet's first billion years
postulate a denser CO2-rich atmosphere than at present. Such an atmosphere should have …

The Raman spectra of a large number of natural feldspar-group minerals were obtained to
determine what compositional and structural information can be inferred solely from their …

Phyllosilicates, one of the five major structural types of silicates, have highly variable
structures and very complex chemistry. This manuscript reports the first comprehensive …

The chemical composition of rocks and soils on Mars analyzed during the Mars Exploration
Rover Spirit Mission was determined by X‐ray analyses with the Alpha Particle X‐Ray …

Clay minerals, or analogously phyllosilicates, are some of the most astonishing minerals
ever discovered on Mars due to their roles as indicators of water-rock interaction. Their …

X-ray fluorescence (XRF) spectroscopy is a well-established and commonly used technique
in obtaining diagnostic compositional data on geological samples. Recently, developments …
