“…3). Following W-E migration across the continental crust the path executes a hairpin to merge with APW defined by uplift exhumation magnetisations from the "Hudsonian" terranes of the North Atlantic region and w1.8 Ga uplift cooling-related magnetisations in dykes and granulite terrane of the North China Shield (Zhang and Piper, 1994;Piper et al, 2011).…”

a b s t r a c tQuasi-integrity of continental crust between Mid-Archaean and Ediacaran times is demonstrated by conformity of palaeomagnetic poles to near-static positions between w2.7e2.2 Ga, w1.5e1.2 Ga and w0.75e0.6 Ga. Intervening data accord to coherent APW loops turning at "hairpins" focused near a continental-centric location. Although peripheral adjustments occurred during Early Proterozoic (w2.2 Ga) and Grenville (w1.1 Ga) times, the crust retained a low order symmetrical crescent-shaped form constrained to a single global hemisphere until break-up in Ediacaran times. Conformity of palaeomagnetic data to specific Eulerian parameters enables definition of a master Precambrian APW path used to estimate the root mean square velocity (v RMS ) of continental crust between 2.8 and 0.6 Ga. A long interval of little polar movement between w2.7 and 2.2 Ga correlates with global magmatic shutdown between w2.45 and 2.2 Ga, whilst this interval and later slowdown at w0.75e0.6 Ga to velocities of <2 cm/year correlate with episodes of widespread glaciation implying that these prolonged climatic anomalies had an internal origin; the reduced input of volcanically-derived atmospheric greenhouse gases is inferred to have permitted freeze-over conditions with active ice sheets extending into equatorial latitudes as established by low magnetic inclinations in glaciogenic deposits. v RMS variations through Precambrian times correspond to the distribution of U-Pb ages in orogenic granitoids and detrital zircons and demonstrate that mobility of continental crust has been closely related to crustal tectonism and incrementation. Both periods of near-stillstand were followed by rapid v RMS recording massive heat release from beneath the continental lid at w2.2 and 0.6 Ga. The first coincided with the Lomagundi-Jatuli isotopic event and led to prolonged orogenesis accompanied by continental flooding and reconfiguration of the crust on the Earth's surface; the second led to continental break-up and instigated the comprehensive Plate Tectonics that has characterised Phanerozoic times. The Mesoproterozoic interval characterised by anorogenic magmatism correlates with low v RMS between w1.5 and 1.1 Ga. Insulation of the sub-continental mantle evidently permitted high temperature melting and weakening of the crustal lid to enable buoyant emplacement of large plutons at high crustal levels during this magmatic event unique to Mesoproterozoic and early Neoproterozoic times.Ó 2012, China University of Geosciences (Beijing) and Peking University.

“…In another contrasting configuration 11,56 , the Indian shield is positioned adjacent to North China and far away from Laurentia. A North China-India connection was also suggested by palaeomagnetism of 1780-1760 Ma dykes 57 and well-dated Xiong'er Group in North China 58 . In an attempt to evaluate these configurations, here we use the two Mesoproterozoic poles along with 1.86 Ga pole reported earlier 17,18 .…”

“…It is noteworthy that other models have been put forward to explain the evolution and tectonic subdivision of the NCC involving different collisional ages/stages and subduction polarities (Zhai et al, 2000Kusky and Li, 2003;Faure et al, 2004;Wang et al, 2004Wang et al, , 2010aZhai, 2004;Polat et al, 2005;Kusky et al, 2007a,b;Li and Kusky, 2007;Trap et al, 2007Trap et al, , 2008Trap et al, , 2009aTrap et al, ,b, 2011Wang, 2009;Santosh et al, 2011;Zhai and Santosh, 2011). Following by the w1.85 Ga amalgamation, the NCC underwent a series of extensional and rifting events in its interior and margins during the time of 1.85e1.6 Ga, forming aulacogens and marginal rift basins with the emplacement of mafic-ultramafic dyke swarms, anorthositeegabbroemangeritee rapakivi granites (AGMR) and A-type granites, and eruption of super-high potassium volcanic rocks (e.g., Halls et al, 2000;Zhai et al, 2000;Lu et al, 2002Lu et al, , 2008Peng et al, 2008;Zhang et al, 2007;Hou et al, 2008;Wang et al, 2008;He et al, 2009;Zhao et al, 2009;Peng 2010;Piper et al, 2011;and references therein).…”

Neoarchean (2.5–2.8Ga) crustal growth of the North China Craton revealed by zircon Hf isotope: A synthesis

The crustal growth of the North China Craton (NCC) during the Neoarchean time (2.5e2.8 Ga) is a hotly controversial topic, with some proposing that the main crustal growth occurred in the late Neoarchean (2.5e2.6 Ga), in agreement with the time of the magmatism, whereas others suggest that the main crustal accretion took place during early Neoarchean time (2.7e2.8 Ga), consistent with the time of crustalformation of other cratons in the world. Zircon U-Pb ages and Hf isotope compositions can provide rigorous constraints on the time of crustal growth and the evolution and tectonic division of the NCC. In this contribution, we make a comprehensive review of zircon Hf isotope data in combination with zircon U-Pb geochronology and some geochemistry data from various divisions of the NCC with an aim to constrain the Neoarchean crustal growth of the NCC. The results suggest that both 2.7e2.8 Ga and 2.5e2.6 Ga crustal growth are distributed over the NCC and the former is much wider than previously suggested. The Eastern block is characterized by the main 2.7e2.8 Ga crustal growth with local new crustal-formation at 2.5e2.6 Ga, and the Yinshan block is characterized by w2.7 Ga crustal accretion as revealed by Hf-isotope data of detrital zircons from the Zhaertai Group. Detrital zircon data of the Khondalite Belt indicate that the main crustal growth period of the Western block is Paleoproterozoic involving some w2.6 Ga and minor Early-to Middle-Archean crustal components, and the crustal accretion in the Trans-North China Orogen (TNCO) has a wide age range from 2.5 Ga to 2.9 Ga with a notable regional discrepancy. Zircon Hf isotope compositions, coupled with zircon ages and other geochemical data suggest that the southern margin may not be an extension of the TNCO, and the evolution and tectonic division of the NCC is more complex GEOSCIENCE FRONTIERS journal homepage: www.elsevier.com/locate/gsf GEOSCIENCE FRONTIERS 3(2) (2012) 147e173 than previously proposed, probably involving multi-stage crustal growth and subduction processes. However, there is no doubt that 2.7e2.8 Ga magmatism and crustal-formation are more widely distributed than previously considered, which is further supported by the data of zircons from Precambrian lower crustal rocks, overlying sedimentary cover, modern river sediments and Late Neoarchean syenogranites. ª 2011, China University of Geosciences (Beijing) and Peking University.
