“…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.…”

“…Its basement gneisses are Mesoarchean to Paleoproterozoic in age, and are partially overlain by Paleoproterozoic to Cenozoic platform cover. The Neoarchean (2.8-2.5 Ga) basement crops out widely and is dominated by ∼2.7-2.5 Ga TTG gneisses and gneissic monzogranites, accounting for 80% of the total Precambrian basement in the TSGT (Jahn et al, 1988;Zhang et al, 2001). Minor ∼2.7-2.6 Ga ultramafic to felsic volcanic and sedimentary rocks, collectively grouped as the Taishan greenstone belt, occur as lenses within the TTG gneisses ( Fig.…”

“…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). However, more precise geochronological data and systematic geochemical investigations of the Late Neoarchean basic-intermediate rocks, coeval with the supracrustal rock suites and intrusive rocks in the Eastern Block, are still rare (Jahn et al, 1988;Yang et al, 2008;Li et al, 2010), especially in the case of 2.60-2.50 Ga magmatism in the Taishan granite-greenstone terrane (TSGT; Jahn et al, 1988;Wang et al, 2009;Peng et al, 2012a).…”

Origin of dyke swarms by mixing of metasomatized subcontinental lithospheric mantle‐derived and lower crustal magmas in the Guocheng fault belt, Jiaodong Peninsula, North China Craton

Cretaceous dyke swarms are widespread in the Guocheng fault belt, Jiaodong Peninsula, eastern North China Craton (NCC). Elemental analyses show that these dykes are classified as high‐K calc‐alkaline to shoshonitic series, and are characterized by high MgO (up to 10.33 wt%; Mg# < 69.8), Cr (<571 ppm) and Ni (<235 ppm) at low silica contents. They are enriched in LILEs (e.g. Sr, Ba, K and Pb) and LREEs, depleted in HFSEs (e.g. Nb–Ta, Zr–Hf, Ti and P), and possess relatively radiogenic Sr (initial 87Sr/86Sr = 0.7078 to 0.7116) and Nd [εNd(t) = −20.8 to −13.5] and much less radiogenic Pb (206Pb/204Pb = 17.13 to 17.56) isotope signatures. These data, combined with inversely zoned amphibole and pyroxene phenocrysts, suggest a hybrid origin for the Guocheng dykes. The inferred magma evolution is dominated by repeated injection of basic magma from metasomatized subcontinental lithospheric mantle (SCLM) into a lower crustal reservoir of intermediate‐felsic composition. This refertilized lithospheric mantle source, probably together with its overlying enriched lower crust, was formed by subduction‐related fluid metasomatism in the Palaeoproterozoic, which resulted from final cratonization of the NCC at ca. 1.8 Ga during assembly of Columbia supercontinent. Our observations also imply that similar mixed magma system with oxidized and sulphur‐rich signatures may be the key to the formation of hydrothermal polymetal deposits and the potential target for mineral exploration in some undiscovered areas.

Crustal reworking in the North China Craton at ~2.5 Ga: evidence from zircon U–Pb age, Hf isotope and whole rock geochemistry of the felsic volcano‐sedimentary rocks from the western Shandong Province

The western Shandong Province (WSP) is one of the typical Neoarchaean granite–greenstone belts in the Eastern Block of the North China Craton (NCC) and is an important region to investigate the early Precambrian evolutionary history of the NCC. The Taishan association, consisting of a ~2.7 Ga komatiite–tholeiite sequence and a ~2.5 Ga felsic volcano‐sedimentary sequence, is the major lithological assemblage in the WSP. In the Qixingtai area, the felsic volcano‐sedimentary sequence, partly subjected to anatexis, is composed of hornblende gneiss, voluminous fine‐grained biotite gneiss and biotite plagioclase gneiss. SHRIMP zircon dating shows that the protolith of the biotite plagioclase gneiss formed after ca. 2.53 Ga. The tonalite intrusion into the volcanic protoliths of the fine‐grained biotite gneiss and biotite plagioclase gneiss occurred at 2.52 Ga. Our age data constrain the time of formation of the felsic volcano‐sedimentary sequence in the Taishan area as 2.53–2.52 Ga. The majority of zircons from the felsic volcano‐sedimentary rocks have intermediate εHf(t) values (−1.2 to +2.1). The whole rock Nd isotopes of the Taishan felsic volcano‐sedimentary rocks yield the εNd(t = 2522 Ma) values of +2.6 to −1.8 and TDM2 ages 3.03–2.68 Ga. These values indicate the pre‐existing crust was reworked at the end of the Neoarchaean (~2.5 Ga). The Taishan felsic volcano‐sedimentary rocks are rhyodacite–dacite and andesite in composition. These rocks and the tonalite display similar high SiO2 (65–72 wt.%) and low MgO (1–2 wt.%) content. In contrast, the minor andesites in the area have lower SiO2 (61–62 wt.%) and higher MgO (5.3–6.3 wt.%), suggesting more mantle contribution during their petrogenesis. However, the Mg‐rich andesites have identical rare earth element and multi‐element patterns with the rhyodacite–dacites and distinguish them from the Taishan sanukitoids. We suggest that the 2.53–2.52 Ga felsic volcanics of the Taishan association are the products of partial melting of a subducted oceanic crust. The andesites were produced by minor modification of the ascending tonalite–trondhjemite–granodiorite‐type magma by the mantle wedge. Our study indicates that (1) the tectonic regime of the WSP greenstone belt was dominated by an arc‐subduction system at ~2.52 Ga and (2) the 2.53–2.52 Ga felsic volcano‐sedimentary rocks and intrusive tonalite are the products of crustal reworking. The felsic volcano‐sedimentary sequence of the Taishan association and other ~2.5 Ga arc‐like assemblages in the NCC provide important clues to understand the nature of the tectonothermal events at the end of the Neoarchaean.
