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.

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.

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.

VOLUMETRIC CHARACTERIZATION OF ZIRCON IN SUPPORT OF DETRITAL GEOCHRONOLOGY

Geological Society of America Abstracts with Programs
Zircon is one of the most studied accessory minerals because of its chemical composition and ability to record events as a geochronometer. It is highly resistant to weathering, which enables it to be transported from source to sink in a sedimentary system.

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,

Assessing reproducibility in detrital geochronology: an inter-laboratory comparison of detrital zircon age spectra

Goldschmidt2025 abstracts
Detrital zircon (DZ) U–Pb geochronology is the most applied technique in single‐grain sedimentary provenance studies. With the advent of ‘big data’ in this field, computational and statistical methods are routinely used to compare detrital age spectra that serve as a provenance barcode for their sedimentary host.Provenance studies of large-scale ...
