Pb-isotopic evidence for an early, enriched crust on Mars

Pb-isotopic evidence for an early, enriched crust on Mars

Martian meteorite NWA 7533 is a regolith breccia that compositionally resembles the Martian surface measured by orbiters and landers. NWA 7533 contains monzonitic clasts that have zircon with U–Pb ages of 4.428 Ga. The Pb isotopic compositions of plagioclase and alkali feldspars, as well as U–Pb iso...
