Thus, the ratio of the daughter to non-radiogenic isotope will become larger with time, while the ratio of parent to daughter will become smaller.
Samarium-neodymium dating is useful for determining the age relationships of rocks and meteorites, based on radioactive decay of a long-lived samarium (Sm) isotope to a radiogenic neodymium (Nd) isotope.
Indeed, the initial amount of the daughter product can be determined using isochron dating.
This technique can be applied if the daughter element has at least one stable isotope other than the daughter isotope into which the parent nuclide decays.
This, in turn, influences the Nd ratio of the isotope system provides important information on crustal formation and the isotopic evolution of the solar system.
