"Red Rocks from Earth to Mars: Stories of diagenesis, crime, art"
Mars is an exciting frontier for sedimentology, with opportunities to discover what might exist within its
sedimentary layers and surface landforms. Comparative studies of red rocks on Earth have provided important clues for interpreting the geology on Mars. Small terrestrial concretions (cemented mineral masses) compared with “blueberries” found on the red planet, helped scientists understand past waters on Mars. Other terrestrial examples of soft-sediment deformation and weathering show remarkable similarities to recent satellite and rover imagery from Mars. Studies of sedimentary context on Earth are critical because terrestrial analogs help us interpret depositional and diagenetic processes, as well as determine where habitable environments for life might exist. In addition, learn how the crime “Case of the Missing Marbles” was resolved, and how an art installation of concretions gives a different perspective of our geoheritage.
