Studying martian igneous samples to constrain the evolution of the martian interior

Rovers and orbiters have allowed us to better understand Mars surficial and other geological processes. Martian meteorites, which are our only samples from this planet, can help constraining magmatic processes that occurred on Mars through precise and accurate Earth-based analyses. Although only 215 meteorites from Mars have been recovered, they have helped us unravel the martian crust and mantle using classic petrological analyses. During her first year in Jezero crater, Perseverance analyzed the igneous Máaz formation (fm), overlying the Séítah fm, which both have been sampled. In this talk we will discuss what our current samples are, what we are missing from our current collection, and what will Jezero igneous samples will teach us about the martian interior.
