The image shows a MAHLI close up image of the Bagnold dunes sand. The first striking thing about the mm-size grains is how rounded they are. That is a crucial feature of wind formed sediments – both recent like Bagnold dunes and ancient like the Stimson rocks.The dune grains have eroded, collected (and abraded to round shapes) the Gale sediments and likely to include pale feldpsar grains and darker pyroxene, olivine and glass.
