  • In recent years, the growing breakthroughs in detrital-zircon U-Pb dating technology have fueled the development of provenance analysis of sedimentary basin, and this approach is further used to analyze paleogeographic environment, basin evolution and unroofing rate of provenance areas. Simultaneously, a number of potential problems that will lead to bias in applying detrital-zircon U-Pb geochronology to provenance analysis have increasingly attracted international attentions. On the basis of summarizing international relevant discussions, this paper concludes such considerations as sample intervals and hydrodynamic fractionation during sampling; reasonable choices of U-Pb dating methods, specific zircons and analytical numbers according to specific science issues during experiments; multi-recycling zircons, zircon-fertility ability, appropriate uplifting time and lag time during provenance comparison, and so on. The last of which is traditionally and simply conducted by matching detrital-zircon age spectrum of sediment units with crystallization age of source rocks in adjacent orogenic belts.

Abstract: In recent years, the growing breakthroughs in detrital-zircon U-Pb dating technology have fueled the development of provenance analysis of sedimentary basin, and this approach is further used to analyze paleogeographic environment, basin evolution and unroofing rate of provenance areas. Simultaneously, a number of potential problems that will lead to bias in applying detrital-zircon U-Pb geochronology to provenance analysis have increasingly attracted international attentions. On the basis of summarizing international relevant discussions, this paper concludes such considerations as sample intervals and hydrodynamic fractionation during sampling; reasonable choices of U-Pb dating methods, specific zircons and analytical numbers according to specific science issues during experiments; multi-recycling zircons, zircon-fertility ability, appropriate uplifting time and lag time during provenance comparison, and so on.
