Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.
