Bowring and others (2007) presented a compilation of high-precision U-Pb zircon ages (both detrital and from ash beds) of the exceptionally well preserved Late Neoproterozoic-Early Cambrian Huqf Supergroup of Oman. Given the general lack of precise geochronological data of the Late Neoproterozoic, the data of Bowring and others (2007) represent an important contribution to the understanding and time calibration of this period of Earth history, which records some highly enigmatic features such as the occurrence of low-latitude glaciations, extreme perturbations of the carbon cycle and the evolution of metazoans. The work by Bowring and others (2007) puts the Huqf Supergroup on the map as one of the geochronologically best constrained sections of its age and makes it an invaluable comparison for other Late Neoproterozoic successions around the world.
