A Review of Research Progress on the Analytical Method of Large-n Detrital Zircon U-Pb Geochronology
Yankuang ceshi, 2022 BACKGROUND Detrital zircon U-Pb geochronology is an important tool for identifying sedimentary provenance and determining the maximum depositional age. The numbers of grains for detrital zircon provenance investigations using laser-ablation inductively ...

Petrogenesis of the Cretaceous Intraplate Mafic Intrusions in the Eastern Tianshan Orogen, NW China
Frontiers in Earth Science, 2021 In this study, we conducted zircon U-Pb dating, and whole-rock geochemical and Sr-Nd isotope analyses on the Late Mesozoic dolerite dykes in the Bailingshan Fe deposit (Eastern Tianshan Orogen, NW China) to unravel their petrogenesis and regional ...

Hf isotopic compositions of the standard zircons for U-Pb dating
Chinese Science Bulletin, 2004 Using the newly published Yb isotopic abundances and the mass bias relationship between Yb and Hf, we carried out an analysis of Hf isotopes in the standard zircon 91500 by means of 193 nm laser attached to Neptune multi-collector ICP-MS (LA-MC-ICPMS).

Two pulse intrusive events of the Pliocene Tanigawa-dake granites revealed from zircon U–Pb dating
Earth, Planets and Space, 2021 We performed zircon U–Pb dating on the Pliocene Tanigawa-dake granites (Makihata and Tanigawa bodies) and the Cretaceous Minakami quartzdiorite, Northeast Japan Arc.

Dating the megalithic culture of laos: Radiocarbon, optically stimulated luminescence and U/Pb zircon results [PDF]
PLOS ONE, 2021 The megalithic jar sites of Laos (often referred to as the Plain of Jars) remain one of Southeast Asia’s most mysterious and least understood archaeological cultures. The sites, recently inscribed as UNESCO World Heritage, host hollowed stone jars, up to three metres in height, which appear scattered across the landscape, alone or clustered in groups ...

Zircon dissolution in a ductile shear zone, Monte Rosa granite gneiss, northern Italy [PDF]
, 2008 The sizes, distributions and shapes of zircon grains within variably deformed granite gneiss from the western Alps have been studied. Zircon shows numerous indicators of a metamorphic response in both the host gneiss and a 5 cm wide continuous ductile ...
