Antarctic alteration as an analogue for processes on Mars – the noble gas perspective

Introduction: Understanding how meteorites residence in cold deserts affects noble gas inventories is integral to our understanding of pre-terrestrial processes. As terrestrial residence ages of up to 1 myr have been seen in Antarctica, terrestrial alteration has to be accounted for and can serve as an analogue for processes on Mars. This study focuses on the changes in the noble gas inventory due to cold desert residences, and links this to processes on the Martian surface and in Martian meteorites
