Radiometric dating - Wikipedia
We have already discussed determining the relative ages of events. We will now discuss absolute age determination, which assigns a quantitative estimate of the number of years ago an event occurred. For a series of horizontal, depositional layers that are not overturned, the relative age of each layer with respect to the other layers may be known by invoking the Law of Superposition: the material on which any layer is deposited is older than the layer itself. Thus, in a series, the layers are successively younger, going from bottom to top.
