Tracing a Wet Past and Diverse Provenances in Gale Crater, Mars, With Lithium Content Using ChemCam on the Curiosity Rover

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The incompatible behavior of Lithium during magmatic differentiation and high mobility during aqueous alteration make it a valuable tracer of crustal processes on Mars. Its preferential incorporation into secondary phyllosilicates further links Li to clay‐forming environments, which are critical for evaluating past aqueous activity and ...
