From the fragments, scientists calculated the relative abundances of elements that shaped as radioactive uranium decayed over billions of years. Thus, sedimentary and metamorphic rocks cannot be radiometrically dated. Although only igneous rocks may be radiometrically dated, ages of other rock varieties may be constrained by the ages of igneous rocks with which they’re interbedded. Approach (i) assumes that the Th/U elemental ratio of the melt is constant, but might differ across totally different grains.
Why are igneous rocks finest for radiometric dating
chemical composition of the magma from which it crystallized.

typically enough (e.g. JCGM, 2008). By default, this is set to 5 × 104 for
