U-Pb and Hf isotopic study of detrital zircons from the Wulashan khondalites: Constraints on the evolution of the Ordos Terrane, Western Block of the North China Craton [PDF]
Earth and Planetary Science Letters, 2006 Detrital zircons from the Wulashan khondalites in the Ordos Terrane, western block of the North China Craton, give U-Pb ages between 1.84 and 2.32 Ga, showing that their provenance was dominated by Paleoproterozoic rocks, much younger than those exposed ...

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

LA-ICP-MS U-Pb geochronology of detrital zircons from the Jining Complex, North China Craton and its tectonic significance [PDF]
Precambrian Research, 2006 LA-ICP-MS U-Pb zircon dating and cathodoluminescene (CL) image analysis were carried out to determine the protolith and metamorphic ages of high-grade Al-rich gneisses, named as "khondalites", from the Jining Complex of the North China Craton (NCC).

Detrital zircon record and tectonic setting [PDF]
Geology, 2012 ABSTRACTDetrital zircon spectra refl ect the tectonic setting of the basin in which they are deposited. Convergent plate margins are charac-terized by a large proportion of zircon ages close to the depositional age of the sediment, whereas sediments in collisional, extensional and intracratonic settings contain greater proportions with older ages that ...

Provenance study of Phanerozoic rocks from the Cordillera Real of Bolivia
Brazilian Journal of Geology, 2021 U/Pb ages of detrital zircon from two samples of Ordovician sediments were determined and, based on similar published data, were compared with xenocrystal inheritance of Triassic and Oligocene granitoids of the Cordillera Real in order to better ...

Nature of zircon clastics in the Riphean and Vendian sandstones of the Southern Urals
Georesursy, 2019 New age dates of detrital zircons of terrigenous rocks augmented the possibilities of interpretation of their provenance. Unfortunately this interpretation is restricted by a formal comparison of age-and-composition characteristics of detrital crystals ...
