Formation and Evolution of Archean Continental Crust of the North China Craton
Yusheng Wan,Dunyi Liu,Chunyan Dong,Hangqian Xie,Alfred Kröner,Mingzhu Ma,Shoujie Liu,Shiwen Xie,Peng Ren +8 more
TL;DR: In this paper, the authors proposed a new tectonic model to understand the formation and evolution of the early Precambrian basement of the North China Craton (NCC), which is based on the compilation of a large database of zircon ages as well as whole-rock Nd isotopic and Hf-in-zircon isotopic data.
Journal ArticleDOI
A Palaeoproterozoic tectono-magmatic lull as a potential trigger for the supercontinent cycle
Christopher Spencer,J. Brendan Murphy,J. Brendan Murphy,Christopher L. Kirkland,Yebo Liu,Ross N. Mitchell +5 more
TL;DR: In this article, a global compilation of mafic igneous rocks demonstrates that this episode of magmatic quiescence was terminated about 2.2 billion years ago by a flare-up of juvenile magmatism.
Journal ArticleDOI
Geochemical and geochronological study on the Paleoproterozoic rock assemblage of the Xiuyan region: New constraints on an integrated rift-and-collision tectonic process involving the evolution of the Jiao-Liao-Ji Belt, North China Craton
Jin Liu,Jian Zhang,Zhenghong Liu,Changqing Yin,Chen Zhao,Zhuang Li,Zhongjie Yang,Shiyong Dou +7 more
TL;DR: Zhang et al. as discussed by the authors presented new field mapping results, U-Pb zircon ages, and geochemistry of the Paleoproterozoic rock sequence (i.e. volcano-sedimentary rocks and gneissic granites) from the Xiuyan area of the Central JLJB.
Journal ArticleDOI
Petrology, phase equilibria modelling and zircon U–Pb geochronology of Paleoproterozoic mafic granulites from the Fuping Complex, North China Craton
Li Tang,Li Tang,M. Santosh,M. Santosh,Toshiaki Tsunogae,Toshiaki Tsunogae,Tatsuya Koizumi,Xin-Kai Hu,Xue-Ming Teng +8 more
TL;DR: In this paper, a clock-wise P-T path is defined for the subsequent retrograde stages based on relatively higher H2O contents from P/T-M(H2O) diagrams, with the peak mineral assemblages comprising garnet + clinopyroxene + amphibole + quartz + plagioclase + K-feldspar + ilmenite ± orthopyroxenes ± magnetite.
Journal ArticleDOI
Tectonic evolution of a complex orogenic system: Evidence from the northern Qinling belt, Central China
TL;DR: In this article, a suite of orthogneisses from the Taihua Group (THG) and Tietonggou Group (TGG) were investigated for their ages.

Composition of the Continental Crust
Roberta L. Rudnick,Shan Gao +1 more
TL;DR: In this paper, the present-day composition of the continental crust, the methods employed to derive these estimates, and the implications of continental crust composition for the formation of the continents, Earth differentiation, and its geochemical inventories are discussed.
Journal ArticleDOI
The composition of the continental crust
TL;DR: In this paper, a new calculation of the crustal composition is based on the proportions of upper crust (UC) to felsic lower crust (FLC) to mafic lower-crust (MLC) of about 1.6:0.4.

Three natural zircon standards for u‐th‐pb, lu‐hf, trace element and ree analyses
M. Wiedenbeck,P. Allé,Fernando Corfu,William L. Griffin,M. Meier,F. Oberli,A. von Quadt,J.C. Roddick,W. Spiegel +8 more
TL;DR: In this paper, the results of a study to develop natural zircon geochemical standards for calibrating the U-(Th)-Pb geochronometer and Hf isotopic analyses are reported.
Journal ArticleDOI
Atlas of Zircon Textures
TL;DR: In this paper, a selection of both the most typical, but also of the less common, features seen in zircon, categorized according to the different geological processes responsible for their formation are presented.
