RUDN 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

Geoscience Data JournalU–Pb dating of detrital zircon is widely used in geology to identify the source of sediments and constrain palaeogeography and tectonic history. We collected the detrital zircon from the Paleoproterozoic to early Palaeozoic strata to understand the North

Journal 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.

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

Detrital zircon age distributions in Bayes-Hilbert spaces
Journal of Geochemical ExplorationA 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 ...

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 ...

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

, 2023 The mineral rutile geochronology is a new method to discriminate different sedimentary tectonic environments. The paleogeography of the South China during the Neoproterozoic to early Palaeozoic remains controversial. This paper presents a first attempt to integrate detrital rutile and detrital zircon U-Pb age data from sandstones of South China.
