Since epsilon units are finer and therefore a more tangible representation of the initial Nd isotope ratio, by using these instead of the initial isotopic ratios, it is easier to comprehend and therefore compare initial ratios of crust with different ages. Nd isotope ratios are used to provide information on the source of igneous melts, as well as to provide age data. Encyclopedia of Scientific Dating Methods. Chondritic meteorites are thought to represent the earliest unsorted material that formed in the Solar system before planets formed.
The usefulness of Sm—Nd dating is the fact that these two elements are rare earths. In the general case:
