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 ...

An algorithm for U–Pb geochronology by secondary ion mass spectrometry [PDF]
Geochronology, 2022 Abstract. Secondary ion mass spectrometry (SIMS) is a widely used technique for in situ U–Pb geochronology of accessory minerals. Existing algorithms for SIMS data reduction and error propagation make a number of simplifying assumptions that degrade the precision and accuracy of the resulting U–Pb dates. This paper uses an entirely new approach to SIMS

Geochemistry, Geophysics, Geosystems, 2021 Detrital geochronology provides insight into a broad range of Earth Science questions. However, detrital zircon U‐Pb age distributions are inherently univariate, and thus quantitative comparison methods are limited to one‐dimension (1D) and subject to ...

A Sample Characterization Toolkit for Carbonate U-Pb Geochronology [PDF]
, 2020 Abstract. Laser ablation U-Pb analyses of carbonate (LAcarb) samples has greatly expanded the potential for U-Pb dating to a variety of carbonate producing settings. Carbonates that were previously considered impossible to date using isotope dilution methods may preserve domains that are favorably interrogated when using spatially resolved laser ...

Navigating the complexity of detrital rutile provenance: methodological insights from the Neotethys Orogen in Anatolia [PDF]
GeochronologySedimentary provenance is a powerful tool for reconstructing convergent margin evolution. However, single mineral approaches, like detrital zircon, have struggled to track sediment input from mafic and metamorphic sources.

Paleozoic ocean plate stratigraphy unraveled by calcite U-Pb dating of basalt and biostratigraphy
Communications Earth & Environment, 2022 The formation and tectonic evolution of mafic oceanic crust can be determined through dating of calcite amygdules using U-Pb geochronology as well as geochemistry and biostratigraphic observations, according to a study of the New England Orogen ...
