During natural radioactive decay, not all atoms of an element are instantaneously changed to atoms of another element. Absolute radiometric dating present in the rock can be used. Generally a shorter half-life leads to a higher time resolution at the expense of timescale. Radiometric dating is a means of determining the "age" of a mineral specimen by determining the relative amounts present of certain radioactive elements.
