    We present the mineralogy of four rocks determined by the CheMin X‐ray diffraction instrument onboard the rover. The results exhibit evidence of multiple diagenetic events, including aqueous alteration by warm groundwaters ...

D.; Rampe, Elizabeth; Schmidt, Mariek; Thompson, Lucy; VanBommel, Scott J.;;;; (American Geophysical Union, 2021-03-10)
    Using data from Curiosity's instrument suite, we show that the tridymite‐bearing rocks exhibit similar chemical patterns with silicon‐rich alteration zones which crosscut the layered sediments. We infer that the tridymite ...

    A layer of weathering‐resistant material is located within the walls of an erosional gully of the Pu'u Poliahu cinder cone in the summit region of Maunakea volcano (Hawai'i). The volcanic cone, initially composed of unaltered ...

    Curiosity's recent traverse through an active basaltic eolian deposit, informally named the Bagnold Dune Field (Figure 1), provided the opportunity for a multi‐instrument investigation of the geomorphology, chemistry, and ...

    The Mars Science Laboratory Curiosity rover performed an extensive campaign on Vera Rubin Ridge (VRR) to determine the geologic history of the ridge. Mineralogical data collected by the CheMin instrument of four rock samples ...
