The epsilon Nd (${ϵ}_{Nd}$) is a widely used parameter to understand the processes of rock forming, i.e. petrogenetic processes from both geochemical and geochronological approach. By definition, ${ϵ}_{Nd}$ is the difference of ${}^{143}Nd{/}^{144}Nd$ of rock sample and ‘chondritic uniform reservoir’ at the time in the past T. For a rock of age T, ${ϵ}_{Nd}\left(T\right)$ is the ‘initial’ value of ${ϵ}_{Nd}$; the value at the time of crystallization of the rock, and…
