    Aqueously altered igneous rocks sampled on the floor of Jezero crater, Mars by Bosak, Tanja

    Published 2023
    “…We report observations of the crater floor, below the crater’s sedimentary delta, finding that the floor consists of igneous rocks altered by water. The lowest exposed unit, informally named Séítah, is a coarsely crystalline olivine-rich rock, which accumulated at the base of a magma body. …”
