Exact excerpt

Our conclusions demonstrate that the texture and chemistry of the Margin unit explored at high elevations are indicative of a slowly cooled, crystalline, olivine-rich ultramafic body. Near the Jezero Western fan, the East Margin exhibits clear indicators of sedimentary reworking, while the base of the North Margin unit shows evidence of polymict debris-flow deposits.
