Abstract

Abstract

Pb, Sr, Nd and Hf isotopes are heavy stable isotopes of radioactive origin, and occurs no isotopic fractionation in geological process, so their isotopic compositions are only related to the source. Therefore, these isotopic compositions are important indicators of material source and tectonic setting, especially in the study of crust-mantle separation and interaction. Some geologists have not systematically studied the theory of isotopic geochemistry, and the calculation of the parameters of those isotopic compositions involves the relatively complex formula derivation, which inevitably leads to errors in data processing in the understanding of formulas and parameters. This paper introduced the related parameters of Pb, Sr, Nd and Hf isotopes, and the calculation formulas of these parameters. On this basis, a set of computer program is designed by using Excel VBA which is user-friendly, convenient, reliable.
