Petrology of NWA 7533: Formation by Impacts on Ancient Martian Crust

Petrology of NWA 7533: Formation by Impacts on Ancient Martian Crust

NWA 7533 contains FeNi grains (~1μm), up to 4.5% Ni in pyrite, and 500 nm Os-Ir-rich particles. Lithic clasts are pyroxenite, norite and zircon-bearing monzonite. The impact melt can be modeled as a mixture of crystal clasts and is poor in monzonite.
