Mineral-scale Sr isotope variation in plutonic rocks – a tool for unraveling the evolution of magma systems.
Isotope ratios of elements such as Sr, Nd, Pb and Hf can be used as tracers of magmatic sources and processes. Analytical capabilities have evolved so that isotope ratios can now be analysed in situ, and isotopic tracers can therefore be used within single minerals to track the changing magmatic env...
