Thermoluminescence of zircon: a kinetic model [PDF]

, 2003
The mineral zircon, ZrSiO4, belongs to a class of promising materials for geochronometry by means of thermoluminescence (TL) dating. The development of a reliable and reproducible method for TL dating with zircon requires detailed knowledge of the ...

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 ...

Detrital zircon and apatite (U‐Th)/He geochronology of intercalated baked sediments: a new approach to dating young basalt flows [PDF]

, 2011
Simple numerical models suggest that many basaltic lava flows should sufficiently heat the sediments beneath them to reset (U‐Th)/He systematics in detrital zircon and apatite.

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 ...

Lithology and provenance of late Eocene - Oligocene sediments in eastern Taranaki Basin margin and implications for paleogeography [PDF]

, 2009
The latest Eocene and Oligocene was a time of marked paleoenvironmental change in Taranaki Basin, involving a transition from the accumulation of coal measures and inner shelf deposits to the development of upper bathyal environments. Up until the end of

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 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 ...
