Neoarchean siliceous high-Mg basalt (SHMB) from the Taishan granite–greenstone terrane, Eastern North China Craton: Petrogenesis and tectonic implications

“…1a; Liu et al, 1992;Jahn et al, 1988;Li et al, 2005Li et al, , 2011bLuo et al, 2004Luo et al, , 2008Wu et al, 2005c;Li and Zhao, 2007;Zhou et al, 2008c;Tam et al, 2011Tam et al, , 2012a. The Eastern Block is dominated by ∼2.6-2.5 Ga diorite, granodiorite, monzogranite, K-feldspar granite plutons and syntectonic charnockites, with subordinate ∼2.7-2.6 Ga TTG gneisses and mafic-ultramafic igneous rocks and minor 2.55-2.50 Ga bimodal volcanic and sedimentary supracrustal rocks (Zhao et al, 1998(Zhao et al, , 2001Wu et al, 2005cWu et al, , 2008Yang et al, 2008;Jiang et al, 2010;Li et al, 2010;Wan et al, 2011Wan et al, , 2012. At present, the oldest known basement within the craton is located in the Eastern Block, which has been dated at 3.8 Ga (Liu et al, 1992(Liu et al, , 2008Wu et al, 2005bWu et al, , 2008Nutman et al, 2011).…”

“…This includes the occurrence of voluminous TTG series and subduction-related sanukitoids and adakitic intrusive rocks (Jahn et al, 1988;Cao et al, 1996;Zhang et al, 2001;Yang et al, 2008;Wang et al, 2009;Wan et al, 2011Wan et al, , 2012Peng et al, 2012a). Several recent studies have revealed two major crust-forming episodes in the Eastern Block of the NCC, mainly based on U-Pb geochronology and Nd-Hf isotope model ages for the Late Archean supracrustal suites and associated rocks (Jahn et al, 1988;Zhao et al, 2001;Wu et al, 2005c;Polat et al, 2006b;Yang et al, 2008;Wan et al, 2011).…”

Growth rate of continental crust in the northeast margin of the North China Craton: Constraints from the U-Pb dating and Lu-Hf isotopes of detrital zircons from the Laoha River

“…The North China Craton is one of the oldest rocks in the word. Major progress in understanding the geological history and tectonic division of North China Craton has been made in the past few years Guo et al, 2012;Jian et al, 2012;Wan et al, 2012b;Zhao and Guo, 2012). The oldest age of rock in the North China Craton is 3.8 Ga, which have been found in the Anshan area of Liaoning Province (Liu et al, 1992;Song et al, 1996;Wan et al, 2005), and the oldest zircon age in the North China Craton is ca.…”

“…Because the fluvial sediment composition can reveal information about provenances of sediments, and zircons from fluvial sediments can be resistant to chemical weathering and mechanical abrasion, so they can survive weathering from their protoliths to river mouths where a single sample can provide information about the sources of an entire river basin (Rino et al, 2004;Wang et al, 2009;Yang et al, 2009). In the last decades, although extensive investigations have been carried out on the formation and evolution of the North China Craton, which led to discovery three Paleoproterozoic continent-continent collisional belts (Khondalite Belt, Trans-North China Orogen and Jiao-Liao-Ji Belt) (Wan et al, 2000(Wan et al, , 2006a(Wan et al, , 2012bZhao et al, 2000Zhao et al, , 2011Guan et al, 2002;Guo et al, 2005Guo et al, , 2012Xia et al, 2006;Zhang, J. et al, 2006Zhang, J. et al, , 2007Zhang, J. et al, , 2009Zhang, J. et al, , 2012Jian et al, 2012;Zhao and Guo, 2012), most of these investigations were focused on tectonic processes operative during the amalgamation of microcontinental blocks along these collisional belts, but few studies were concentrated on the accretion of the North China Craton, and especially on the accretion rates. Yang et al (2006) applied fluvial sediments to constrain the evolution of continental crust in China.…”

“…Some models suggested that the NCC became a single crustal block at ca. 2.5 Ga, then experienced rifting during the middle Paleoproterozoic, and was then consolidated, resulting in cratonization during late Paleoproterozoic [2][3][4][5][6][7][8][9]. Other models proposed that the NCC only became a single tectonic unit in the late Paleoproterozoic [10][11][12][13][14][15][16][17][18][19][20].…”
