Yellow River's Contribution to the Building of Yangtze Delta During the Last 500 Years ‐ Evidence From Detrital Zircon U‐Pb Geochronology

Geophysical Research Letters, 2021
The Yangtze Delta (YD), as one of the world mega deltas, its formation process has long been the subject of research. Previous study has proposed a remote connection of the Yellow River (YR) to the building of the YD over the past 600–400 years. However,

When did the Pyrenean shortening end? Insight from U–Pb geochronology of syn‐faulting calcite (Corbières area, France)

Terra Nova, 2021
Absolute dating helps to define the age and duration of orogen building. Here we present new U–Pb ages of syn‐faulting calcites collected in the northern foreland basin of the Pyrenees.

Rodinia: the evidence from integrated palaeomagnetism and U–Pb geochronology

Precambrian Research, 2001
Abstract Of many hundreds of well-defined palaeomagnetic poles that have been reported from cratons around the world in the 1700–500 Ma period, only a few are precisely dated. However, such ‘key’ palaeopoles are a prerequisite for establishing rigorous palaeomagnetic reconstructions in order to chart the assembly, drift and breakup of the postulated ...

U–Pb geochronology of the eastern Hall Peninsula, southern Baffin Island, Canada: a northern link between the Archean of West Greenland and the Paleoproterozoic Torngat Orogen of northern Labrador

Precambrian Research, 1999
Abstract A corridor east of Iqaluit that crosses several regionally significant lithologic boundaries has been mapped and sampled for geochronology. Zircon, monazite and titanite were analysed by the isotope dilution U–Pb method to characterize igneous and metamorphic events, and Pb–Pb ages of detrital zircons were determined by laser ablation ...
