A database of detrital zircon U–Pb ages and Hf isotopes for the Middle East (Iranian and Arabian plates)

open access: yesGeoscience Data Journal
The detrital zircon records significant information in the ‘source‐sink’ system. With the application of in situ laser ablation technology, a large number of high‐quality detrital zircon data have been published since 2000.

Earth's middle age [PDF]

open access: yes, 2014
This research was funded through Natural Environment Research Council (grant NE/J021822/1) and the APC was paid through the RCUK OA block grant.Earth's middle age, extending from 1.7 to 0.75 Ga, was characterized by environmental, evolutionary, and ...

Provenance and drainage system of the Early Cretaceous volcanic detritus in the Himalaya as constrained by detrital zircon geochronology

open access: yesJournal of Palaeogeography, 2015
The age range of the major intra-plate volcanic event that affected the northern Indian margin in the Early Cretaceous is here defined precisely by detrital zircon geochronology.

Detrital zircon age distributions in Bayes-Hilbert spaces

open access: yesJournal 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]

open access: yesGeology, 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.

Detrital zircon geochronology of pre-Tertiary strata in the Tibetan-Himalayan orogen [PDF]

open access: yes, 2011
Detrital zircon data have recently become available from many different portions of the Tibetan-Himalayan orogen. This study uses 13,441 new or existing U-Pb ages of zircon crystals from strata in the Lesser Himalayan, Greater Himalayan, and Tethyan ...

Destabilization of Long‐Lived Hadean Protocrust and the Onset of Pervasive Hydrous Melting at 3.8 Ga

open access: yesAGU Advances, 2022
The nature of Earth's earliest crust and crustal processes remain unresolved questions in Precambrian geology. While some hypotheses suggest that plate tectonics began in the Hadean, others suggest that the Hadean was characterized by long‐lived ...

Palaeotethys-related sediments of the Karaburun Peninsula, western Turkey: constraints on provenance and stratigraphy from detrital zircon geochronology [PDF]

open access: yes, 2017
Detrital zircon U–Pb geochronology of 15 Late Palaeozoic to Early Mesozoic siliciclastic sandstones from the Karaburun Peninsula in western Turkey determines maximum sedimentation ages, identifies possible source areas, and anchors the study area within ...

Ages of detrital zircons from lower Cambrian sandstones of North-Eastern periphery of the East European platform - sings of provenances of Ediacaran - early Cambrian Mezen basin

open access: yesRUDN Journal of Engineering Research, 2014
The detrital zircons were delivered from sandstones of Brusov Fm. of Mezen basin. Absence of detrital zircons with 750-510 Ma and availability of two distinct populations - Paleoproterozoic and Archean - with ages resembled well known ages of crystalline

Cadomian/Pan-African consolidation of the Iberian Massif assessed by its detrital and inherited zircon populations: is the ~610Ma age peak a persistent Cadomian magmatic inheritance or the key to unravel its Pan-African basement?

open access: yesGeologica Acta, 2022
This work assessed the age distribution of Cadomian/Pan-African orogenic events (550-590 and 605-790Ma, respectively) in several zones of Iberian Massif by means of detrital and inherited zircon analysis compilation. Detrital zircon age spectra show that
