- •
ChemCam/Curiosity provides elemental composition at Gale crater’ lower Mt Sharp.
- •
Diagenetic features in fine-grained sediments show diverse textures and compositions.
- •
Presence of Mg-, Fe-, Ca-sulfates and fluorite is deduced from ChemCam chemistry.
- •
Multiple phases of aqueous alteration suggest a complex post-depositional history.
