Temporal and spatial variations of Mesozoic magmatism and deformation in the North China Craton: Implications for lithospheric thinning and decratonization

A short-lived but significant Mongol–Okhotsk collisional orogeny in latest Jurassic–earliest Cretaceous

“…The prominent gap between Late Jurassic and Early Cretaceous magmatic episodes in the Great Xing'an ranges, northeast China W.L. Xu et al, 2013), North China Block Zhang et al, 2014), and eastern China (Wu et al, 2005b) was probably related to this collision event (Fig. 2).…”

“…2, 11A). A continental arc formed along the western continental margin of Amuria and provided sediments for the rifted Mohe Basin to the southwest (He et al, 2005;Zhang et al, 2014). All Upper Jurassic volcanic rocks in the Great Xing'an ranges and the northern margin of the North China Block (Figs.…”

Reconstruction of northeast Asian deformation integrated with western Pacific plate subduction since 200 Ma

“…1 and 2) were characterized by intracontinental shortening, which formed basement-involved fold-and-thrust and flexural basins, and the structural deformations in the Yanshan Mountains serve as models (e.g., Liu, 1998;Liu et al, 2007;Wang et al, 2008;Zhang et al, 2011;Liu et al, 2013;Zhang et al, 2014). The deformed Xingshikou Formation, which mostly consists of conglomerate, unconformably overlies Paleozoic and Proterozoic strata (Liu et al, 2007).…”

Middle–Late Mesozoic sedimentary provenances of the Luxi and Jiaolai areas: Implications for tectonic evolution of the North China Block

“…Additionally, Yang et al (2013) regarded the Sulu orogen as the source of the Late Triassic and the Neoproterozoic (mainly ranging in 850-1000 Ma, with a peak at 948 Ma) zircons in the Mesozoic sediments of the Luxi area. Actually, the occurrence of the Late Triassic magmatic rocks is confined to the northeastern corner of the Sulu orogen Liu and Liou, 2011), but they occur extensively in the NNCB (Zhang et al, 2010(Zhang et al, , 2014, and those Neoproterozoic zircon ages are older than the diagnostic mid-Neoproterozoic ages (750-850 Ma) of the Sulu orogen (Liu and Liou, 2011). Despite the controversy, it is important to recognize that the Jurassic sediment provenances have received an increasing supply from a mixed source of the NNCB and XMOB from the Early Jurassic to the Late Jurassic, which was confirmed by integrated studies of detrital zircon geochronology, bulk-rock geochemistry , and sandstones detrital modal analysis (Xu et al, 2013b).…”
