Zircon Hf evolutionary patterns are powerful tools to investiage magma petrogenesis and crustal evolution. The 176Hf/177Hf isotopic signature of a rock is particularly informative and can be used to derive an estimation of the time when mantle extraction and diagnose closed system reworking where su...
