A Combination of Single Zircon Dating by TIMS and Cathodoluminescence Investigations on the Same Grain: The CLC Method — U-Pb Geochronology for Metamorphic Rocks

  • Ulrike Poller
Chapter

Abstract

An essential question in geoscience is the age of a rock. Geochronologists use different isotopic systems to obtain age information about geological events. The UTh-Pb system is used in many cases to determine the time of crystallisation. Until now, there have been several U-Pb dating procedures: the conventional one (Krogh 1973; Oberli et al. 1981; Steiger et al. 1993), the Pb-Pb evaporation method (Kober 1986, 1987), the vapour digestion method (Wendt and Todt 1991) and SHRIMP (sensitive high resolution ion microprobe; Compston et al. 1986; Gebauer et al. 1989).
