From the fragments, scientists calculated the relative abundances of components that formed as radioactive uranium decayed over billions of years. Thus, sedimentary and metamorphic rocks cannot be radiometrically dated. Although only igneous rocks could be radiometrically dated, ages of other rock types can be constrained by the ages of igneous rocks with which they are interbedded. Approach (i) assumes that the Th/U elemental ratio of the melt is fixed, but may differ throughout completely different grains.
Why are igneous rocks greatest for radiometric dating
