Iron Mobility During Diagenesis at Vera Rubin Ridge, Gale Crater, Mars
Résumé
→ Images from the Curiosity rover show the presence of dark-toned diagenetic features at Vera Rubin ridge → ChemCam analyses of these features point towards a Fe-oxide composition, consistent with crystalline hematite → Depletion of Fe and Mn in bleached halos surrounding the high-Fe diagenetic features indicates mobility of Fe and Mn during the later stages of diagenesis
