DETRITAL ZIRCON POPULATIONS OF THE EASTERN LAURENTIAN MARGIN IN THE APPALACHIANS

Geological Society of America Abstracts with Programs, 2020
Abstract Newly compiled U-Pb detrital zircon data from eight geographic domains along the eastern Laurentian margin from Newfoundland (Canada) to Alabama (United States) show a highly consistent signature along strike, with only minor local variations. The Precambrian signature is characterized by a small ca.

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.

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)

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 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.

Metamorphic zircon: tracking fluid pathways and the implications for the preservation of detrital zircon

Journal of the Geological Society, 2013
Zircon in greenschist-facies Dalradian metasedimentary rocks of Scotland is characterized by two types: large detrital grains and small euhedral metamorphic grains. The former are concentrated in psammites and contain abundant evidence of dissolution and reaction with metamorphic fluids. The smallest metamorphic microzircons (<9 µm
