Keywords:zircon, Hf isotope, U-Pb dating

The U-Pb zircon dating have been determined by the constraints of formation (or depositional) age of various rocks and provenance analysis of clastic rocks. However, there are some problems that are difficult to discuss only with U-Pb zircon dates. I think that some of these problems can be solved by measuring Hf isotopes of zircon. In this presentation, I will introduce some of the usefulness of the measured Hf isotopes of zircon.
