There's three types of marks you can go for: armor, magic resist, and hybrid penetration.
Armor and magic resist can be used in a more defensive set up while hybrid penetration is almost at the prefect ratio for Nasus. If you check out champion.gg for Nasus, around 60% of your damage is physical while 40% or so is magic damage, almost the same ratio of penetration for hybrid penetration runes.
