| Abstract: |
The JPL rover Perseverance's investigations of Jezero crater's floor reveal that the ultramafic Séítah formation and the overlying mafic Máaz formation are deformed into a broad, low‐amplitude structural dome. Mastcam‐Z stereo images processed into digital outcrop models, together with RIMFAX ground‐penetrating radar profiles, were used to reconstruct the three‐dimensional stratal geometry of both units along a SW–NE transect across a southern domain of the dome called south Séítah. Measurements from 3‐D reconstructions show a progression from sub‐horizontal layers in the central parts of the dome to dips |
