Project Details
Description
Some researchers propose that granite compositions reflect those of their source rocks, and therefore can be used to map the deep Earth. Others disagree, arguing that granites are produced by mixing between continental crust and magma rising from the mantle. We aim to resolve this dispute and test the validity of such deep Earth mapping by using new techniques for in situ micro-analysis of Hf, O and U-Pb isotopes in granite zircon (an indicator of the age and origin of the granite s source) to determine whether mantle magma mixing played a significant role in producing the internationally recognised type-example granites of SE Australia.
