Viscosity and Flow Properties of the Seitah Olivine-Rich Lithology
One of the most surprising findings of the Perseverance rover was the discovery of olivine cumulate in the Séítah region [1]. The rover landed and traversed to the Séítah region and collected measurements at three workspaces: Bastide, Brac and Issole (Fig 1). Here we use the SuperCam VISIR and LIBS to investigate the properties of the lithology insitu and determine two things: 1) the olivine-clay-carbonate regional lithology is low in Al3+, which allows us to eliminate the possibility of clays which are high in Al3+, 2) the viscosity of the Séítah formation is extremely low, which is a reasonable explanation for the Séítah unit to both cumulate and thin-layered (Fig 1b).
