Two Types of Archean Continental Crust: Plume and Plate Tectonics on Early Earth

Martin J. Van Kranendonk

Over 4.5 billion years, Earth has evolved from a molten ball to a cooler planet with large continental plates, but how and when continents grew and plate tectonics started remain...

Accretionary Orogen and Evolution of the Japanese Islands: Implications From a Sr-Nd Isotopic Study of the Phanerozoic Granitoids From SW Japan
Bor-Ming Jahn
The Japanese Islands represent a segment of a 450 Ma old subduction-related orogen developed along the western Pacific convergent margin, and most tectonic units are composed of late Paleozoic to...

Delamination/thinning of Sub-Continental Lithospheric Mantle Under Eastern China: The Role of Water and Multiple Subduction
B. F. WindleyS. MaruyamaW. J. Xiao
We present a new model to explain one of the biggest tectonic problems of Earth Sciences today, namely, how and why did the Archean sub-continental lithospheric mantle under the Eastern...

40Ar/39Ar Thermochronology of High-Pressure Granulite Nappes in the Southern Brasília Belt, Brazil: Implications for Nappe Exhumation
Barry L. RenoMichael BrownPhilip M. Piccoli
Neoproterozoic orogenesis in the southern sector of the Southern Brasília Belt was the result of subduction and terminal collision between the Socorro–Guaxupé Arc and Paranapanema Block to the west (present...

Paleomagnetism of the 765 Ma Luakela Volcanics in Northwest Zambia and Implications for Neoproterozoic Positions of the Congo Craton
Michael T. D. WingateSergei A. PisarevskyBert De Waele
The 765 Ma Luakela volcanics of northwest Zambia are a northeast-trending belt of basaltic to andesitic flows within an essentially undeformed and unmetamorphosed siliciclastic succession that unconformably overlies Neoarchean and...

Volgo-Uralia: The First U-Pb, Lu-Hf and Sm-Nd Isotopic Evidence of Preserved Paleoarchean Crust

Svetlana V. BogdanovaBert De WaeleElena V. BibikovaElena A. BelousovaAlexander V. PostnikovAnna A. FedotovaLubov' P. Popova

The crustal segment Volgo-Uralia is the least known part of the East European Craton. Its crystalline crust is hidden beneath a thick Neoproterozoic to Phanerozoic cover but disclosed by thousands...

Zircon Ages and Metamorphic Evolution of the Archean Assegaai–De Kraalen Granitoid-Greenstone Terrain, Southeastern Kaapvaal Craton

Lopamudra SahaAxel HofmannHangqiang XieErnst HegnerAllan WilsonYusheng WanDunyi LiuAlfred Kröner

The Assegaai, De Kraalen and Witrivier greenstone belts in the southeast part of the Kaapvaal craton contain strongly deformed volcano-sedimentary successions affected by amphibolite- to granulite-facies metamorphism at ∼3.22 to...

The ∼390 Ma high-T Metamorphic Event in the Chinese Altai: A Consequence of Ridge-Subduction?

Yingde JiangMin SunGuochun ZhaoChao YuanWenjiao XiaoXiaoping XiaXiaoping LongFuyuan Wu

High-grade rocks occur in the Chinese Altai, but the timing of metamorphism is poorly constrained, which hinders our understanding of the thermo-tectonic history of the region. Representative high-grade samples from...

Zircon Ages, Sr-Nd-Hf Isotopic Compositions, and Geochemistry of Granitoids Associated With the Northern Ophiolite Mélange of Central Cuba: Tectonic Implication for Late Cretaceous Magmatism in the Northwestern Caribbean
Yamirka Rojas-AgramonteAlfred KrönerAntonio García-CascoTony KempErnst HegnerMireya PérezMatthias BarthDunyi LiuAlain Fonseca-Montero
The geology of Cuba is representative of the orogenic belt fringing the northwesternmost margin of the Caribbean plate. It is characterized by a tectonic collage made up of a continental...

Metamorphism of the Lüliang Amphibolite: Implications for the Tectonic Evolution of the North China Craton
Guochun ZhaoChangqing YinJinghui GuoMin SunSanzhong LiXuping LiChunming WuChaohui Liu
The Lüliang Complex is located in the southern sector of the Trans-North China Orogen, a continent-continent collisional belt along which the discrete Archean Eastern and Western blocks amalgamated to form...

Juvenile Magmatism and Crustal Recycling at the End of the Neoarchean in Western Shandong Province, North China Craton: Evidence From SHRIMP Zircon Dating
Yusheng WanDunyi LiuShijin WangChunyan DongEnxiu YangWei WangHongying ZhouZhenguo NingLilin DuXiaoyan YinHangqiang XieMingzhu Ma
Western Shangdong Province experienced major crustal growth as a result of 2.75 to 2.50 Ga tectonothermal events, different from other Archean areas in the North China Craton. Besides early Neoarchean...

Early Archean Crust of the Middle Dnepr and Azov Domains, Ukrainian Shield—evidence From Ages of Detrital Zircons in Mesoarchean Greenstone Belts
E. BibikovaS. ClaessonA. FedotovaG. ArtemenkoL. Ilyinsky
To clarify the early evolution of the Ukrainian Shield we have dated detrital zircons, separated from metasedimentary rocks of Mesoarchean greenstone belts from the Middle Dnepr and Azov domains (Ukrainian...
