A review of U-Pb detrital zircon systematics from Cambrian- Lower Devonian rocks of the Moroccan Meseta

Geogaceta, 2022
U-Pb geochronological analysis of detrital zircon grains is a powerful tool to decipher the pre-Mesozoic paleogeography. In this work, we present a sediment provenance study based on a compilation of 41 Cambrian-Early Devonian siliciclastic samples from

Detrital Avalonian zircons in the Laurentian Southern Uplands terrane, Scotland [PDF]

Geology, 2003
The Silurian–Ordovician Southern Uplands terrane occupies a key position in the Caledonian orogen, yet its genesis is controversial. Marginal-basin, backarc, and forearc tectonic regimes have all been invoked as operative at the Laurentian margin of the Iapetus Ocean.

A database of detrital zircon U–Pb ages and Lu–Hf isotope of sediments in the South China Sea

Geoscience Data Journal
Source‐to‐sink analysis examines the effects of source areas and basin (sink) dynamics on the generation, transport, composition, distribution and deposition of sediment in modern and ancient sedimentary systems.

Detrital zircon U-Pb geochronology of sediments from the Okinawa Trough: implications for sedimentary provenance

Frontiers in Earth Science
In order to distinguish terrestrial material sources in the Okinawa Trough (OT), this study analyzed four surface sediment samples from the northern, middle, and southern parts of the OT using detrital zircon U-Pb age analysis.

Two‐Dimensional Quantitative Comparison of Density Distributions in Detrital Geochronology and Geochemistry

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 ...

Evidence for ca. 2046 Ma high-grade metamorphism in Paleoproterozoic metasedimentary rocks of the northern Borborema Province, NE Brazil: constraints from U-Pb (LA-ICP-MS) zircon ages

Journal of the Geological Survey of Brazil, 2019
This study presents LA-ICP-MS U-Pb detrital zircon ages on a migmatitic paragneiss of the Jaguaretama Complex, northern Borborema Province, NE-Brazil.

Local Singularity Spectrum: An Innovative Graphical Approach for Analyzing Detrital Zircon Geochronology Data in Provenance Analysis

Fractal and Fractional
Detrital zircon geochronology plays a crucial role in provenance analysis, serving as one of the fundamental strategies. The age spectrum of detrital zircons collected from the sedimentary unit of interest is often compared or correlated with that of ...

Detrital zircon age distributions in Bayes-Hilbert spaces

Journal of Geochemical Exploration
A growing number of researchers in the Earth Science community use the information provided by the Usingle bondPb ages of detrital zircon in sedimentary environments, be these modern (sediments) or ancient (sedimentary or metasedimentary rocks). This information is key to understanding detritus's past and present flow on Earth and its attendant ...

The role of detrital zircons in Hadean crustal research

Lithos, 2014
Abstract Meso-Archean sedimentary sequences at Mt. Narryer and the Jack Hills of the Narryer Terrane in Western Australia's Yilgarn Craton contain detrital zircon grains with ages as old as 4.37 Ga, the oldest preserved terrestrial matter. These grains are rare remnants of Hadean (4.5–4.0 Ga) terrestrial crust and their survival stems from the ...

Detrital zircon U–Pb ages of the Upper Vindhyan sequence from the Bhander Sandstone of the Bhopal Inlier in Central India and its implications for provenance of the Vindhyan Basin

Journal of the Palaeontological Society of India
This study presents the detrital zircon U–Pb ages of the Upper Bhander Sandstone from the Bhopal Inlier, Central India. The age spectra of Upper Bhander Sandstone show the dominance of a detrital zircon population between 1,500 and 1,900 Ma, a ...
