A Review of Research Progress on the Analytical Method of Large-n Detrital Zircon U-Pb Geochronology

open access: yesYankuang 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

open access: yesFrontiers 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

open access: yesChinese 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).

Dating the megalithic culture of laos: Radiocarbon, optically stimulated luminescence and U/Pb zircon results [PDF]

open access: yesPLOS 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 ...
