| Description: |
International audience ; Since Landing in Jezero crater, the Mars 2020 Perseverance rover has encountered over 4,000 light-toned float rocks (“float”) scattered across the dark-toned, mafic to ultramafic crater floor and volcaniclastic Jezero delta. To date (Sol ~1100), no outcrop of these light-toned float has been found. Here, we use imaging, chemical, and mineralogical data from the SuperCam and Mastcam-Z instruments onboard the Perseverance rover to constrain the potential origins of these unusual float.Geochemical data acquired from the SuperCam laser induced breakdown spectrometer (LIBS) shows that these rocks are rich in Al2O3 (up to 44 wt%), with low abundances of MgO, FeOT, CaO and Na2O (averages |
