Clues from Martian meteorites for the evolution of CO2 and H2O on Mars
Models suggest that during the Noachian (4.1-3.7 Ga), Mars may have had a thick CO2-rich atmosphere and surface water. Here we report our findings from the Martian nakhlite meteorites which identify the first direct evidence of a CO2 sequestration mechanism on Mars, the timescale of water-rock interaction and the history of water during the late Amazonian (<700 Ma).
Tea and coffee will be available after the seminar.
The astrobiology seminar series is run by the UK Centre for Astrobiology based in the School of Physics & Astronomy. Astrobiology is a multi-disciplinary subject and the seminar series actively encourages attendance by undergraduates, postgraduates and academic staff from other departments..
