On Mars, billion-year-old sedimentary rocks containing clay minerals are key indicators of ancient habitable environments and may preserve organic compounds. On Earth, where plate tectonics drives the burial and heating of rocks, clay minerals are transformed into new minerals, influencing organic preservation, and impacting global geochemical cycling of carbon, oxygen, and water. Mars lacked plate tectonics for much of its history, but data from Mars Science Laboratory Rover, . Charles Nye¹ Ghanashyam Neupane² Scott Quillinan¹.
