Re-discussion on the detrital zircon provenance of the lower Yanchang Formation in the southern Ordos Basin

open access: yesOpen Geosciences, 2016
The Ordos Basin is the second largest sedimentary basin in China. The Yanchang Formation is the key oilbearing layer in the Ordos Basin. The stratigraphic time interval and the stratigraphic division of the Yanchang Formation has been highly debated with

Resolution of the age structure of the detrital zircon populations of two Lower Cretaceous sandstones from the Weald of England by fission track dating [PDF]

open access: yes, 2017
Modes in the frequency of distribution of fission track ages obtained from detrital zircon grains may prove characteristic of individual sandstone bodies, supporting the identification of the sources from which a particular flow of sedimentary detritus ...

Resolving Paragneiss Provenance at Grollier Lake in the Athabasca Granulite Terrane, Western Canadian Shield [PDF]

open access: yes, 2016
U-Pb crystallization ages of metamorphic and detrital zircons from all three paragneiss samples fall into the range of ca. 1.85-2.59 Ga, excluding two much older grains.

U-Pb geochronology of detrital zircon crystals from Caratas and Los Arroyos formations, Northeastern Venezuela.

open access: yesRevista Técnica de la Facultad de Ingeniería, 2014
 LA-MC-ICPMS U-Pb geochronology in detrital zircons was performed in two Tertiary turbidite sequences from Northeastern Venezuela to contribute to the understanding of the Cenozoic history of the northern South America plate. The age results of detrital

Stratigraphy, Geochronology and Detrital Zircon Provenance of Two Silicic Ash Layers at Hagerman Fossil Beds National Monument, Idaho [PDF]

open access: yes, 2012
Hagerman Fossil Beds National Monument (HAFO) is home to the world-famous Hagerman Horse Quarry. This site gives important insight into Pliocene age paleontology. Absolute ages of this site have been elusive, although researchers have assumed the site to

Temporal and spatial heterogeneity of the Ailaoshan–Song Ma–Song Chay ophiolitic mélange, and its significance on the evolution of Paleo-Tethys

open access: yesComptes Rendus. Géoscience
According to detrital zircons ages spectra and Hf isotopes in the matrix of the ophiolitic mélange, the Ailaoshan–Song Ma–Song Chay Indosinian suture zone can be divided into four units, namely M1, M2, M3, and M4.

Provenance of Detrital Rutiles from the Triassic–Jurassic Sandstones in Franz Josef Land (Barents Sea Region, Russian High Arctic): U-Pb Ages and Trace Element Geochemistry

open access: yesGeosciences
Provenance study plays an important role in paleogeographic and tectonic reconstructions. Detrital zircons are commonly used to identify sediment provenance; however, a wide range of detrital zircon ages in clastic rock often represent a fingerprint of ...
