Tectonic evolution of the North China Craton: introduction

Geochronology and Sr–Nd–Hf isotopes of the Mesozoic granitoids from the Great Xing'an and Lesser Xing'an ranges: implications for petrogenesis and tectonic evolution in NE China

“…), which evolved from the amalgamation of different microcontinental blocks between the Siberian Craton in the north and the North China Craton in the south (Windley et al ., ; Jahn et al ., ; Glorie et al ., ; Zhai and Santosh, , ; D. Li et al ., ). According to previous studies, the evolution of NE China was governed by three successive tectonic regimes: (1) closure of the Palaeo‐Asian Ocean in the Palaeozoic; (2) closure of the Mongol–Okhotsk Ocean in the late Palaeozoic–Mesozoic; and (3) subduction of the western Pacific Plate in the Mesozoic–Cenozoic (Wang and Mo, ; Wu et al ., ; S. Q. Li et al ., ; Zhang et al ., ; Santosh and Somerville, ; Goldfarb and Santosh, ). As a result, a series of E‐, NE‐ and NNE‐trending discordogenic faults were triggered during various evolution stages, providing the passage for the volcanism, magmatism and ore deposition in this area (Liu et al ., ; Chen et al ., ; Zhao et al ., ).…”

“…In recent years, there have been a number of geochronological and geochemical studies of the Mesozoic granitoids in NE China (Jahn et al ., ,, , ; Wu et al ., , , , ; Yang et al ., ; S.R. Li et al ., ; Santosh and Somerville, ; Yang et al ., ). These studies suggest that the Mesozoic granitoids dominantly formed during the Jurassic and the Early Cretaceous, and most of them are characterized by high ϵ Nd (t) and low ( 87 Sr/ 86 Sr) i values, indicating significant continental crustal growth.…”

SIMS zircon U–Pb and molybdenite Re–Os geochronology, Hf isotope, and whole-rock geochemistry of the Wunugetushan porphyry Cu–Mo deposit and granitoids in NE China and their geological significance

“…Their formation and distribution are controlled by the evolution of the earth system, particularly by its progressive cooling and geodynamic evolution from plume-influenced tectonics to modern plate tectonics (Groves and Bierlein, 2007;Y.S. Zhai et al, 2009;Santosh and Somerville, 2013;Zhu et al, 2013;Santosh and Pirajno, 2014). And different metallogenic systems are generally associated with different geodynamic environments (Y.J.…”

Continental dynamics of Eastern China: Insights from tectonic history and receiver function analysis

“…The NCC was cratonized during the Neoarchean-Paleoproterozoic (Zhai and Santosh, 2011; and remained stable since then for several million years, unlike the other Archean cratons of the world (e.g., Morgan, 1984;Boyd et al, 1985;Pollack, 1986;Grand, 1987;Jordan, 1988;Nyblade and Pollack, 1993;Ling et al, 2009). The NCC is bound by the Early Paleozoic Qilianshan Orogen to the west, the Late Paleozoic-Late Mesozoic Central Asian Orogenic Belt to the north and the Qinling-Dabie-Sulu ultrahigh-pressure metamorphic belt to the south (Ren et al, 1987;Zorin et al, 2001;Santosh and Somerville, 2013;Xiao et al, 2013). The NCC incorporates two major Precambrian blocks, the Eastern Block and the Western Block, sutured along a Paleoproterozoic collision zone known as the Trans-North China Orogen (central NCC) Zhai and Santosh, 2011;Zhao and Zhai, 2013;Zheng et al, 2013;.…”
