Zircon U–Pb ages and Lu–Hf isotopes of Paleoproterozoic

201371 Zircon is an ideal mineral for U–Th–Pb dating and Lu–Hf isotopic measurement because it contains moderate U Th and Hf but very low common Pb and Lu Once incorporated into zircon lattice the U–Pb and Lu–Hf systems can hardly be disturbed due to the extremely low diffusion rates of these isotopes eg Cherniak and Watson 2003
