Constraints on Jezero paleolake history from its fluvial input
Résumé
The western fan of Jezero crater displays features interpreted as fluvial and deltaic sedimentary rocks from orbital data [1,2]. Images obtained using the SuperCam Remote Micro-Imager (RMI) and the Mastcam-Z camera provide in-situ observations of Jezero crater’s western fan in various locations along the Perseverance traverse. In the last two years, the rover analyzed the fan front before that it crossed the top of the fan. Here we summarize the
fluvial and deltaic stratigraphy observed throughout the delta and discuss further the variability in the fluvial
input and its implication on the history of Jezero lake.
