The term U–Pb dating normally implies the coupled use of both decay schemes in the 'concordia diagram' (see below).However, use of a single decay scheme (usually Pb) leads to the U–Pb isochron dating method, analogous to the rubidium-strontium dating method.

The radioactive parent elements used to date rocks and minerals are: Radiometric dating using the naturally-occurring radioactive elements is simple in concept even though technically complex.

If we know the number of radioactive parent atoms present when a rock formed and the number present now, we can calculate the age of the rock using the decay constant.

All rocks and minerals contain long-lived radioactive elements that were incorporated into Earth when the Solar System formed.

These radioactive elements constitute independent clocks that allow geologists to determine the age of the rocks in which they occur.

Thus the current ratio of lead to uranium in the mineral can be used to determine its age.
