Remnants of ≥3800 Ma crust in the Chinese part of the Sino-Korean craton

2.24 Ga mafic dykes from Taihua Complex, southern Trans-North China Orogen, and their tectonic implications

“…The North China Craton (NCC), which is the oldest known craton in China and contains massive Archean to Paleoproterozoic rocks (Liu et al, 1992;Zhao et al, 2003), is bounded by the Central Asian Orogenic Belt to the north, the Qinling-Dabie Orogenic Belt to the south, the Kunlun-Qilian Orogenic Belt to the west, and the Su-Lu ultrahigh-pressure Metamorphic Belt to the east (Fig. 1a).…”

“…The North China Craton (NCC), which is the oldest known Craton in China and contains massive Archean to Paleoproterozoic rocks (Liu et al, 1992;Zhao et al, 2003), has been attracting more and more attentions of researchers. Although the tectonic model that the North China Craton was formed by the amalgamation between the Western Eastern Blocks of the NCC along the TransNorth China Orogen (TNCO) has been accepted by most scholars ( Fig.…”

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

“…The Eastern Block is subdivided into the Longgang Block in the northwest and the Langrim Block in the southeast, separated by the Paleoproterozoic Jiao-Liao-Ji Belt ( Fig. 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).…”

“…The Eastern Block of the NCC is an important area in which the oldest rocks in China (∼3.8 Ga) are present (e.g., Liu et al, 1992) and ∼2.75-2.50 Ga crust-forming and tectonothermal events similar to other Archean cratons around the world, have been identified (Nutman et al, 2011;Lü et al, 2012;Sun et al, 2012;Wang et al, 2012;Wu et al, 2012;Zhang et al, 2012a,b). 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).…”
