Pasi rino rine simbi uye nickel. Simbi iyi inofungidzirwa kuti yakapfuma kaviri pazvinhu zvakareruka kupfuura zvePasi. Musimboti uyu wakapoteredzwa nemucheka wesilicate uyo wakaumba zvinhu zvakawanda zve tectonic uye volcanic papasi, asi unoratidzika kunge wakarara. Kunze kwesilicone uye oxygen, zvinhu zvakawandisa muMartian crust is iron, magnesium, calcium, uye potassium. Ukobvu hwepasi rino hwe crust ingangoita 50 km (31 mi), ine ukobvu hwakanyanya hwe 125 km (78 mi).
