UP AND DOWN WENT JEZERO LAKE: SIGNIFICANT RESULTS FROM THE FIRST EVER SEQUENCE STRATIGRAPHIC ANALYSIS ON MARS
Résumé
Since the landing of the Perseverance rover in February 2021, remote observations of the main delta front and its remnant, the Kodiak butte (Fig. 1), took place until the rover drove out of sight. These imaging campaigns have been critical in i) confirming the Gilbert-delta nature of the sedimentary fan [1, 2] ii) assessing the depositional
settings of the area [2] and even iii) proposing discharge rates for associated fluvial activity [3]. Here, we summarize our findings regarding the first ever sequence stratigraphic analysis on another planet than Earth, based on Kodiak observations [2]. We notably highlight fluctuations of the lake-level in the order of 5-10m occurring at the time of Kodiak build-up.
