However, the mechanisms, timing, and global importance of this process are unconstrained, in part because the remnants of ancient serpentinizing systems have not been examined in situ. New geochemical and mineralogical data from multiple instruments aboard the Mars 2020 Perseverance rover record serpentinization and associated H\n 2\n production in ancient igneous rocks of the Máaz formation, exposed on the Jezero crater floor. These data, combined with petrogenetic constraints, indicate that serpentinization may have been driven by devolatilization of magmatic H\n 2\n O, highlighting a potential link between H\n 2\n production and the style and tempo of magmatism within the ancient martian crust.\n ","url":"https://innscience.ca/es/community/literature/cf99f377-1c1e-4997-bfbb-e59c70feea95"}
