“…Therefore, the Late Triassic time possibly represented a phase of erosion and exhumation of magmatic arcs and unroofing of the collisional orogen due to postorogenic collapse along the Solonker suture zone in southeastern CAOB (Figure 12c). This scenario is also supported by postorogenic extension in the Late Triassic in eastern CAOB [Wu et al, 2002;Davis et al, 2009;Li et al, 2013a; W. L. and intraplate extension along northern margin of the North China Craton during the Late Triassic to Early Jurassic [Yang et al, 2006[Yang et al, , 2012a[Yang et al, , 2012bZhang et al, 2014].…”

Detrital zircon U-Pb dating of the Xingfuzhilu Formation in southern Inner Mongolia yields a maximum depositional age of around 220 Ma. The predominantly Permian and Triassic zircons are characterized by oscillatory zoning and euhedral shapes, with mostly positive zircon ε Hf (t) values (+2.0 to +16.4), indicating that they were derived from a proximal magmatic source. Early-Middle Paleozoic zircons have variable zircon ε Hf (t) values from À6.2 to +11.2 and are characterized by weak oscillatory zoning and subhedral-subrounded shapes, suggesting that the sources are a proximal magmatic arc, possibly mixed with components of the Ondor Sum magmatic arc and the magmatic arc at the northern margin of the North China Craton. The remnants of Precambrian blocks in the southeastern Central Asian Orogenic Belt (CAOB), and the North China Craton may also have been a minor source region for the Xingfuzhilu succession. These results, combined with regional data, indicate that a closing remnant ocean basin or narrow seaway possibly existed in the Middle Permian (Guadalupian) immediately prior to final collision of the CAOB and closure of the Paleo-Asian Ocean. Subsequent collision resulted in the crustal uplift and thickening along the Solonker suture zone, accompanied by possible slab break-off and lithospheric delamination during the Latest Permian to Middle Triassic. The resultant orogen in the Late Triassic underwent exhumation and denudation of rocks in response to the postorogenic collapse and regional extension. Vertical crustal growth in the Triassic is documented by detrital zircons from the Xingfuzhilu Formation and appears to have been widespread across entire eastern CAOB.

In recent decades, the Yanshanian movement in the Mesozoic has been a hotspot of much geological research, attracting numerous studies focusing on regional tectonics, basin evolution, and associated magmatism and volcanic activities. The Haifanggou Formation, exposed in Xingcheng Basin, which is one of intracontinental basins in western Liaoning Province, North China Craton (NCC), comprises mainly conglomerates dominated with interbedded sandstone. Although palaeontology, stratigraphy and lithofacies have been established, its mineralogical compositions and geochronology, even the provenance and implications for Yanshanian movement are still poorly discussed. Available sandstone samples provided a unique opportunity to study the genesis and further deciphered the tectonic mechanisms. The sandstone types of Haifanggou Formation are dominantly litho‐feldspathic litharenite and litharenite. Modal sandstone analysis shows that the origin and deposition mainly are due to arid to semi‐arid weathering and recycling of older rocks and magmatic arcs, eroded and transported debris from eastern NCC. Our new detrital zircon U–Pb ages exhibit that the maximum depositional ages of the Haifanggou Formation were conservatively estimated as late Middle Jurassic (165.6 ± 3.1 Ma). The detrital zircon U–Pb age spectrum of this formation is dominated by several peaks that indicate a provenance from the surrounding rocks including the basement of NCC. The sedimentation of the Haifanggou Formation is deposited under compressional tectonics as a local response of the Yanshanian movement which was related to the subduction of Palaeo‐Pacific Plate.

“…However, the magmatism is mainly concentrated in the northeastern part of the study area (Figure ). Previous studies have revealed that the Late Triassic granites in the Liaodong area mainly formed by post‐orogenic delamination (Yang, Sun, Zhang, & Wilde, ), which could explain why the magmatism was concentrated on one side of the North China Block. Accordingly, it is speculated that the granites in the North Korea Block had a similar cause.…”

Early Mesozoic intracontinental deformation in the eastern North China Block: Implication for an indentation model of North China to South China blocks

The Qinling‐Dabie‐Sulu Orogen was formed by the collision of the North and South China blocks during the Indosinian Period. The intracontinental deformation was subsequently developed during the Late Triassic to Early Jurassic in the northeastern, eastern, and southeastern parts of eastern North China Block with different structural patterns. In this paper, we present structural analysis of the Indosinian deformation in the western Shandong and southern Liaoning provinces and synthesized the previous studies of the Triassic‐Early Jurassic deformation in different areas of the eastern North China Block, from the northeastern, central to southeastern parts. Integrating the previous studies of petrology, geochronology, and geophysics, we suggested that (1) a series of top‐to‐the‐northwest thrust‐nappes were formed in the Sulu Orogen, and the southeastward antithetic faults developed in the South China Block. In the eastern North China Block, the Indosinian intracontinental deformation is intensely developed near the orogenic belt as thrust‐nappes and away from the belt developed open folds. (2) The present‐day structural lines in the northeastern, central, and southeastern parts of eastern North China Block show the S‐N‐, E‐W‐, and NE‐trending lines, respectively. It could be the structural response to the dynamics of an orocline or indentation induced by Triassic collision of the North and South China blocks; (3) the eastern margin of the North China Block subducted southeastward beneath the South China Block along the Wulian‐Qingdao‐Yantai Fault during the Indosinian Period.
