U-Pb and Hf isotopic study of detrital zircons from the Hutuo group in the Trans-North China Orogen and tectonic implications

open access: yes, 2011
There is a broad consensus that the North China Craton formed by the amalgamation of the Western and Eastern Blocks along the nearly N-S trending Trans-North China Orogen.

Late Devonian-Early Carboniferous magmatism in the Lhasa terrane and its tectonic implications: Evidences from detrital zircons in the Nyingchi Complex

open access: yes, 2016
The Late Paleozoic tectonic evolution of the Lhasa terrane remains poorly understood due to the paucity of the Late Paleozoic magmatic rocks exposed at the surface.

Age and Sources of Late Precambrian Sedimentary Sequences of the Southern Baikal Region: Results of the U–Pb LA-ICP-MS Dating of Detrital Zircons

open access: yes, 2013
The first data on the age of detrital zircons are given for Late Precambrian terrigenous rocks of the Baikal Group and Ushakovka Formation of the southern flank of the Siberian Craton.

Progressive development of the Paleocene to early Miocene Shimanto accretionary complex in eastern Shikoku, Southwest Japan: response to magmatic arc evolution along the East Asian continental margin

open access: yesProgress in Earth and Planetary Science
Evolution of the Shimanto accretionary complex suggests implications for the geological history of the East Asian continental margin. To better understand the tectonic evolution of the complex during Paleocene to early Miocene, we collected new ...

The Early Permian active continental margin and crustal growth of the Cathaysia Block: In situ U–Pb, Lu–Hf and O isotope analyses of detrital zircons

open access: yes, 2012
Late Permian to Triassic (“Indosinian-aged”) orogenesis and associated magmatism are widespread in southeastern China, but their causes and significance to the regional geodynamic evolution are highly controversial.

The Proterozoic Pogor’uy Formation of Yenisei Ridge: Age and Provenance Sources According to U/Pb Dating of Detrital Zircons [PDF]

open access: yes, 2019
The results of U–Pb-isotopic dating of detrital zircons from sandstones of the Proterozoic Pogor’uy Formation, occurring to the north and south of the East Angara block of Yenisei Ridge, are presented.

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 ...

open access: yesЛитосфера, 2016
The data on U-Pb-isotopic ages of detrital zircons from Riphean-Paleozoic and Early Triassic sandstones and geochemistry of shales and mudstones of the Western Urals are discussed.
