Precambrian protoliths and Early Paleozoic magmatism in the French Massif Central: U–Pb data and the North Gondwana connection in the west European Variscan belt [PDF]

open access: yes, 2010
International audienceU–Pb geochronological data were collected on zircon by LA-MC-ICP-MS on orthogneiss and paragneiss from the Limousin area in the French Massif Central (FMC), in order to investigate the connection between the west European Variscan ...

Geology and Geochemistry of Hadean Zircon Bearing Supracrustals from Quad Creek, Eastern Beartooth Mountains (Montana, USA) [PDF]

open access: yes, 2011
Quad Creek Paleoarchean quartzites (~3300 Ma) in Montana contain \u3e3900 Ma detrital zircons. The outcrop-scale geological and geochemical context of these rocks is not well documented.

Linkages between the southern Patagonia Pre-Permian basements: new insights from detrital zircons U-Pb SHRIMP ages from the Cerro Negro District

open access: yesGeologica Acta, 2014
The Patagonian basement rocks are dominated by Precambrian to Early Paleozoic metamorphic rocks intruded by Paleozoic granitoids. Recently discovered basement rocks in the Cerro Negro District are characterized mainly by quartz-muscovite-chlorite schists;

The Relationships between Greenstone Belts and the Kryvyi Rih–Kremenchuk Basin in the Middle Dnieper Domain of the Ukrainian Shield Revealed by Detrital Zircon

open access: yesGeosciences
Detrital zircons from two samples of metasandstones from the Lykhmanivka Syncline, Middle Dnieper Domain of the Ukrainian Shield (Skelevate Formation of the Kryvyi Rih Group), have been dated by the LA-ICP-MS U-Pb method. Metasandstones from the northern

Provenance records of the North Jiangsu Basin, East China: Zircon U–Pb geochronology and geochemistry from the Paleogene Dainan Formation in the Gaoyou Sag

open access: yesJournal of Palaeogeography, 2014
Detailed zircon U–Pb dating and whole-rock geochemical analyses were carried out on the sedimentary rocks of the Paleogene Dainan Formation from Gaoyou Sag in the North Jiangsu Basin, East China. Whole-rock rare earth element characteristics suggest that

A Triassic to Cretaceous Sundaland–Pacific subduction margin in West Sarawak, Borneo [PDF]

open access: yes, 2017
Metamorphic rocks in West Sarawak are poorly exposed and studied. They were previously assumed to be pre-Carboniferous basement but had never been dated. New 40Ar/39Ar ages from white mica in quartz-mica schists reveal metamorphism between c.

The provenance of Borneo's enigmatic alluvial diamonds:A case study from Cempaka, SE Kalimantan [PDF]

open access: yes, 2016
Gem-quality diamonds have been found in several alluvial deposits across central and southern Borneo. Borneo has been a known source of diamonds for centuries, but the location of their primary igneous source remains enigmatic.

Exploring the use of zircon geochronology as an indicator of Laurentide Ice Sheet till provenance, Indiana, USA [PDF]

open access: yes, 2017
A pilot study was designed to evaluate the potential of zircon geochronology as a provenance indicator of till from the Lake Michigan, Saginaw, and Huron-Erie Lobes of the Laurentide Ice Sheet. Based on existing ice flow-path models, we hypothesized that
