U‐Pb dating of zircon by LA‐ICP‐MS [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2006
In this study we used LA‐ICP‐MS (laser ablation–inductively coupled plasma–mass spectrometry) to determine U‐Pb ages of 5 zircon samples of known age (∼1800 Ma to ∼50 Ma) in order to determine the reproducibility, precision, and accuracy of this geochronologic technique.

Radiometric dating of Middle Pleistocene carbonates: assessing consistency and performance of the U–Th and U–Pb dating methods [PDF]

open access: yesGeochronology
The U–Th and U–Pb dating methods are widely employed for radiometric dating of Pleistocene carbonates, such as speleothems and corals. The U–Th dating method has been progressively refined over recent decades, largely through advances in mass ...

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 ...

Element Fractionation and Correction Method for U-Pb Dating of Titanite by Laser Ablation-Inductively Coupled Plasms-Mass Spectrometry

open access: yesYankuang ceshi, 2020
BACKGROUND Isotope geochronology is a basic subject to explore the temporal and special evolution of geological bodies and geodynamics. The U-Pb dating technology of accessory minerals is the most widely used in isotope geochronology.
