THE MARTIAN SEDIMENTARY ROCK RECORD: RECENT ADVANCES IN OUR UNDERSTANDING OF DEPOSITIONAL PROCESSES AND ENVIRONMENTS
Résumé
Sedimentary rocks on Mars preserve a record of past depositional and diagenetic conditions that offers an opportunity to investigate the planet’s geologic and climate history beyond the limits of the geomorphic and impact crater records. Since 2019, new rover and orbiter observations and analyses of the Martian sedimentary record, along with sediment transport modeling advances, have provided important insights into the environment, climate, and habitability of early Mars. This review presents: (1) key advances in Martian sedimentology and stratigraphy over the past 5 years, (2) current limitations, and (3) priority areas for future research.
