The date measured reveals the last time that the object was heated past the closure temperature at which the trapped argon can escape the lattice. Sedimentary rocks in particular are notoriously radioactive-free zones. For this reason, many archaeologists prefer to use samples from short-lived plants for radiocarbon dating.
However, it can be used to confirm the antiquity of an item. If a layer of sedimentary rock is nearer to the surface, then that layer was formed much more recently. Choose a relative no closer than second cousin.
