This paper summarizes Li, Fe, and Mg isotope studies on igneous rocks and minerals, as representative of NTSI geochemistry. Li isotopes have been widely applied to the studies of mantle geochemistry, recycling of subducted materials, and metamorphism to constrain the source of magma and kinetic diffusion process. Fe isotope fractionation is related to partitioning of multi-valent Fe between Fe-bearing phases, which can occur in the course of mantle metasomatism, partial melting, and fractional crystallization. Mg isotopic compositions of igneous rocks most likely reflect the source signatures. Variation of Mg isotopic ratios of mantle peridotites is trivial and this provides a homogenous background for Mg isotope fractionation in low temperature processes. Furthermore, Cl, Si, Cu, Ca, and U isotopes are also promising in the future geochemical studies.
