From source to sink in central Gondwana: Exhumation of the Precambrian basement rocks of Tanzania and sediment accumulation in the adjacent Congo basin [PDF]

, 2016
Apatite fission track (AFT) and (U-Th)/He (AHe) thermochronometry data are reported and used to unravel the exhumation history of crystalline basement rocks from the elevated (>1000 m above sea level) but low-relief Tanzanian Craton.

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 ...

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.

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

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.

Early Cenozoic drainage evolution in the Jianghan Basin: Constraints from detrital zircon U-Pb ages of surface rivers and cores in the basin

地质科技通报, 2023
Objective The evolution of large rivers is closely linked to the interactions between tectonic and climatic processes. Understanding the evolutionary history of these rivers is crucial for uncovering the influence of deep dynamic processes on the Earth's

Thermal history of the early Miocene Waitemata Basin and adjacent Waipapa Group, North Island, New Zealand [PDF]

, 1999
Apatite fission track (AFT) and vitrinite reflectance (VR) data for early Miocene outcrops from the Waitemata Basin reveal that the basin sequence was subjected to shallow burial before denudation.

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 ...
