Late Paleozoic provenance shift in the south-central North China Craton: Implications for tectonic evolution and crustal growth

Provenance and tectonic-paleogeographic evolution: Constraints from detrital zircon U–Pb ages of Late Triassic-Early Jurassic deposits in the northern Sichuan basin, central China

“…However, the southern NCB is found to expose magmatic rocks with the 270 Ma age peak ( Fig. 9a; Li et al, 2010b;Li and Huang, 2013;Shi et al, 2013, and references therein;Zhu et al, 2014), which is most likely to correlate with the detrital zircons in both the western, southern and eastern Sichuan basin and the SGT of Middle-Upper Triassic.…”

“…It is noted that in a paleo-uplift zone in Inner Mongolia along the northern margin of the NCB, which is 1500 km away from the Late Triassic Sichuan foreland basin, large amounts of magmatic rocks with age peaks at 270 Ma are exposed and mostly display negative e Hf (t) values . Additionally, ubiquitous detrital zircons with similar ages and isotope compositions in the Permian-Triassic strata in the southern NCB were generally considered to derive from the paleo-uplift zone in Inner Mongolia (Li et al, 2010b;Zhu et al, 2014). However, the southern NCB is found to expose magmatic rocks with the 270 Ma age peak ( Fig.…”

Provenance of detrital zircons in the Late Triassic Sichuan foreland basin: constraints on the evolution of the Qinling Orogen and Longmen Shan thrust-fold belt in central China

“…In fact, the PermianTriassic strata in the southern North China Block also contain a large number of detrital zircons with similar age and isotope compositions. These detrital zircons in the southern North China Block were generally suggested to be sourcing from the palaeo-uplift in Inner Mongolia (Li et al 2010a;Li and Huang 2013;Zhu et al 2014) …”

“…the Qinshui and Jiyuan basins; Peng and Wu 2006;Li 2013;Zhu et al 2014). These strata in the relict of the inner Craton basin and southern North China Block have been investigated using detrital zircon U-Pb geochronology and Lu-Hf isotope studies ( Figure 9a).…”

Mid-Paleozoic arc granitoids in SW Japan with Neoproterozoic xenocrysts from South China: New zircon U–Pb ages by LA-ICP-MS

“…Recent studies on detrital zircon geochronology in South China have clarified the abundant occurrence of Archean-Mesoproterozoic zircon grains, in addition to the dominant Neoproterozoic ones, within the Cambrian to Ordovician sandstones (e.g. Jin, 2002;Darby and Gehrels, 2006;Liu et al, 2008;Wang et al, 2010;Zhu et al, 2014). These age spectra of detrital zircon in South China show striking similarity to those of the Ordovician-Silurian sandstones in Japan (Nakama Shimojo et al, 2010;Okawa et al, 2013;, whereas those from North China are different, in particular, in lacking Neoproterozoic grains.…”
