Coupled Zircon-Rutile U-Pb Chronology: LA ICP-MS Dating, Geological Significance and Applications to Sediment Provenance in the Eastern Himalayan-Indo-Burman Region

open access: yesGeosciences, 2019
U-Pb dating by LA ICP-MS is one of the most popular and successful isotopic techniques available to the Earth Sciences to constrain timing and rates of geological processes thanks to its high spatial resolution, good precision (absolute U/Pb age ...

Review in Zirconology. I. Progress in U-Pb dating of zircon.

open access: yesJOURNAL OF MINERALOGY, PETROLOGY AND ECONOMIC GEOLOGY, 1993
In this paper (Part I), recent progress in U-Pb dating of zircon is reviewed. Rare-earth element (REE) partitioning of accessory minerals and REE geochemistry of zircon will be reviewed in separate papers, Part II and Part III, respectively. Zircon (ZrSiO4) is one of the most important minerals in geochronology because the zircon crystal is very ...

Data on recovery rates and external morphologies of zircon grains from mechanical and electrical pulverization of rock samples

open access: yesData in Brief, 2018
In this data article, we provide information on the recovery rate and scanning electron microscope (SEM) images of the external morphology of zircon grains separated from two rock samples (AS3 and TEMORA 2) using both mechanical and electrical ...

Review of geothermochronological and thermobarometric techniques for the construction of cooling and exhumation curves or paths for intrusive igneous rocks

open access: yesBoletín Geológico, 2020
The present study reviews radiometric and thermobarometric techniques used to construct cooling curves or paths to characterize intrusive bodies and to calculate cooling and exhumation rates. To construct these curves or paths, the temperature, time and

Quantifying Long‐Term Reproducibility of Zircon Reference Materials by U‐Pb LA‐ICP‐MS Dating

open access: yesGeostandards and Geoanalytical Research, 2022
Inter‐session excess variance of U/Pb and Pb/Pb ratios in LA‐ICP‐MS zircon dating is the largest contributor to systematic errors, which in turn limit the accuracy of age determinations. Quantifying long‐term excess variance of reference materials allows for the estimation of excess variance in samples, but such compilations are not available in the ...

Comparison of SHRIMP U-Pb dating of monazite and zircon

open access: yesChinese Science Bulletin, 2004
Monazite dating is an important technique in geochronological studies. However, monazite U-Pb dating by SHRIMP is much less popular than zircon in geochronological applications. This paper compares the results of SHRIMP U-Pb dating of monazites and zircons separated from two granite samples, indicating that monazite SHRIMP U-Pb dating at the Beijing ...

Pre-Variscan evolution of the Western Tatra Mountains: new insights from U-Pb zircon dating [PDF]

open access: yesMineralogy and Petrology, 2011
In situ LA-MC-ICP-MS U-Pb zircon geochronology combined with cathodoluminescence imaging were carried out to determine protolith and metamorphic ages of orthogneisses from the Western Tatra Mountains (Central Western Carpathians). The metamorphic complex is subdivided into two units (the Lower Unit and the Upper Unit).
