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.

Detrital-zircon geochronology of the northeastern Tibetan plateau

Geological Society of America Bulletin, 2003
U-Pb geochronologic analyses have been conducted on 413 detrital-zircon grains collected from 16 samples in the Altun Shan, Nan Shan, and Qilian Shan. The samples come primarily from quartz arenites and metaturbidites of Middle to Late Proterozoic age and from feldspathic and volcanic clast-rich sandstones of early Paleozoic age.

Detrital Zircon Analysis of the Sedimentary Record

Reviews in Mineralogy and Geochemistry, 2003
The composition of “heavy,” or accessory, detrital minerals in sediments and sedimentary rocks has been a topic of quantitative study for at least the last seventy years, beginning with the first issue of the Journal of Sedimentary Petrology in May 1931 (Tyler 1931, Pentland 1931).

Detrital zircon reference for the North China block

Journal of Asian Earth Sciences, 2006
Abstract U–Pb analyses of 250 single detrital zircons from Upper Proterozoic to Ordovician strata collected from the Zhuozi Shan in north-central China provide a detrital zircon reference for the North China block, a major crustal entity in the Asian tectonic collage.

Detrital Zircon U-Pb Geochronology Applied to Tectonics

Annual Review of Earth and Planetary Sciences, 2014
Detrital zircon geochronology is rapidly developing into an essential tool in Earth science research because of the widespread occurrence of zircon in sedimentary systems; the wide range of information that can be extracted from zircon crystals; the ability to determine ages with reasonable precision, accuracy, and efficiency; and the wide range of ...

U‐Pb Detrital Zircon Analysis – Results of an Inter‐laboratory Comparison

Geostandards and Geoanalytical Research, 2013
Inter‐laboratory comparison of laser ablationICP‐MSandSIMSU‐Pb dating of synthetic detrital zircon samples provides an insight into the state‐of‐the art of sedimentary provenance studies. Here, we report results obtained from ten laboratories that routinely perform this type of work.

Detrital zircon geochronology of a fossiliferous Miocene paleochannel

ABSTRACT A plethora of fauna and flora of uncertain age was recently discovered in fluvial sedimentary rocks of the Mokelumne River drainage of the western Sierra Nevada foothills (California, USA). These fossils are preserved in the Mokelumne paleochannel and show great biodiversity containing mastodon, gomphothere, camel, rhino, horse,
