The deltaic depositional environments and stratigraphy of the kodiak butte (Jezero crater, Mars)
Résumé
For two years, the Perseverance rover has been exploring the Jezero crater floor. A lot of remote observations have been made on the delta front and its remnants, and notably toward the Kodiak butte, situated about 1 km south of the main delta front (Fig. 1). There, morphologies typical of a Gilbert-type delta have been identified [1] using long-distance observations carried out by SuperCam’s Remote Micro-Imager (RMI) and Mastcam-Z (Fig. 2). In this work, we use high-resolution 2D images, as well as 3D Digital Outcrop Models [2;3], to document and characterize the sedimentary succession observed up the cliffs of Kodiak. We divide the Kodiak butte into 3 units (0 to 2) with further sub-facies divisions described below.
