The European continental crust through detrital zircons from modern rivers: biasing effects in the detrital zircon record

2021
We present U-Pb, Lu-Hf, and O isotopic data, as well as size-shape data for approximately 3700 detrital zircons from 15 European rivers. In combination with geomorphological information for each river basin (area, drainage length, and hypsometric curves), we evaluate the representativeness and biases affecting such datasets.

Mineral inclusion assemblage and detrital zircon provenance

Chemical Geology, 2018
Abstract Mineral inclusions are common in magmatic zircon and a potentially rich source of petrologic information. Controls on the relative proportions of inclusion phases, specifically early-crystallizing minerals such as apatite and late-crystallizing phases such as quartz, K-feldspar, and muscovite, have not been systematically studied.

Bias in detrital zircon geochronology and thermochronometry

Chemical Geology, 2013
Abstract Detrital studies that utilize zircon U–Pb geochronology and fission-track (FT) thermochronometry are subject to a range of potential sources of bias that should be properly evaluated and minimized. Some of them are common to any single-grain mineral analysis (e.g., variable bedrock mineral fertility, hydraulic sorting during transport ...

Detrital zircon evidence for the antiquity of Taiwan

Geosciences Journal, 2009
In-situ U-Pb geochronology and Hf isotopic studies of zircons from the Pre-Tertiary basement complex and Eocene rocks of the Central Range of Taiwan were carried out to elucidate the history of detrital zircons older than 2.3 Ga. Zircons from the eastern Backbone Range and Eastern Central Range show Paleoproterozoic to late Neoarchean ages (2.3−≥2.5 Ga)

Detrital zircon geochronology and processes in accretionary wedges

Earth-Science Reviews, 2020
Abstract The detrital zircon U–Pb geochronology has been widely employed to analyze accretionary wedges over the past decade. The goal of this paper is, first, to briefly review this rapidly growing field of research and then to explore the exciting potential of the detrital zircon geochronology for interpreting processes in accretionary wedges.

Persistence of Grenvillian dominance in Laurentian detrital zircon age systematics explained by sedimentary recycling: Evidence from detrital zircon double dating and detrital monazite textures and geochronology

Geology, 2020
AbstractGrenvillian ages dominate Neoproterozoic to Paleozoic detrital zircon (DZ) populations across eastern Laurentia and persist through the present. The persistence of this dominance is inferred to result from recycling of DZ grains ultimately sourced from exceptionally Zr-rich and zircon-fertile Grenvillian granitoids.
