“…Although minor amounts of zircons, with ages of~450 Ma, were found from the basalts and mafic-ultramafic dykes in the southern SQB (C. L. Zhang, Gao, et al, 2007), they cannot yield dominant age peaks. Generally, this population, accompanied with ages of 1,000-900 Ma, is believed to be sourced from the NQB (Liao, Wang, Liu, Wang, & Santosh, 2017; C. L. Zhang et al, 2013). the southern margin of the Central Asian Orogenic Belt (Guan, Li, Zhang, Shi, & Li, 2016;C.…”

“…The zircons from the middle part of the Sunjiagou Formation (Y‐3) show quite different characteristics from the other samples. The U–Pb ages display a large number of Early Palaeozoic and Neoproterozoic components, representative of the typical provenances derived from the NQB (Liao et al, ; C. L. Zhang et al, ). As mentioned above, the major peaks of 400–500 Ma accompanied by 900–1,000 Ma are the two prominent indicators for the source from the granitoid intrusions in the NQB, although minor amounts of Neoproterozoic zircons with age peaks at 753 Ma were also probably contributed by the SQB.…”

“…The Shangdan Ocean is regarded as the long‐term boundary that separated the SCB from the NCB during the Palaeozoic, and northward subduction is thought to have occurred in the Early Cambrian (Dong et al, ; Dong & Santosh, ; Dong, Zhang, Neubauer, et al, ). Although many studies have attempted to constrain the evolution of the Shangdan Ocean, the closure timing of the Shangdan oceanic crust is still widely disputed: (a) The majority of studies agree that the closure was initiated in the Early Devonian (Dong et al, ; Dong & Santosh, ; Meng & Zhang, ; Wu & Zheng, ; S. Yu, Li, Zhao, Cao, & Suo, ) or prior to the Devonian (Liao et al, ; L. Liu et al, ; Shi, Yu, & Santosh, ; Z. J. Zhou et al, ), and subsequent exhumation had occurred within the NQB. The uplift during the Late Carboniferous was likely the inheritance of this Caledonian Orogeny.…”

Basin formation and sedimentary development in the southern North China Craton (NCC) are closely related to the tectonic evolution of the Qinling Orogenic Belt (QOB). With the aim of revealing the coupling evolution between the QOB and southern NCC during the Late Palaeozoic, an investigation based on provenance analysis was performed in this study. We present new detrital zircon U–Pb data from the Middle–Late Permian sediments in the Yiyang area, southern NCC. The results show that detrital zircons, from the Middle Permian Shihezi Formation, have three major peaks at 2,447, 1,905, and 296 Ma. In contrast, the lower and upper parts of the Late Permian Sunjiagou Formation yield major peaks at ~1.85 Ga and ~260 Ma, with weak peaks at ~2.5 Ga, ~450 Ma, and ~315 Ma, and the middle part of the Sunjiagou Formation displays a major peak at 429 Ma. Combined with published palaeocurrent data and lithofacies palaeogeography, the sediments of the Middle Permian Shihezi Formation were sourced from the Inner Mongolia Palaeo‐Uplift along the northern margin of the NCC, whereas the Upper Permian Sunjiagou Formation originated mainly from the southern margin of the NCC including the North Qinling Belt. This provenance shift indicates that the North Qinling Belt and southern margin of the NCC initiated the uplift and exhumation during the Late Permian. On the basis of the evolutionary history of the QOB, we attribute the uplift geodynamics to the Mianlue oceanic crust subduction. This study provides important sedimentological constraints for the tectonic conversion during the Late Palaeozoic along the southern margin of the NCC, which also restricts the start‐up time of the Mianlue oceanic crust subduction from the perspective of the basin–mountain system.

“…Subduction caused tectonic–thermal events in the southern NCC, which we consider to be recorded by the 516‐Ma age group. Ongoing subduction led to generation of voluminous collisional granite at approximately 450 Ma in the northern Qinling Orogenic Belt (Liao, Wang, Liu, Wang, & Santosh, ). The 445‐Ma age group may be derived from these granites.…”

The Tongcheng ultrapotassic rocks intrude in Mesoproterozoic limestones in Chongxin County, Gansu Province, China, at the south‐western margin of the Ordos Block. They are characterized by high K2O and Al2O3 but low SiO2, FeOT, MgO, and CaO. The ultrapotassic rocks are relatively depleted in Nb, Ta, Ti, Zr, and Hf and enriched in the large‐ion lithophile elements Rb, Ba, and Th. Zircons from the ultrapotassic rocks yield an Early Cretaceous U–Pb age of 120 Ma. The slightly enriched whole‐rock Sr and Nd isotopic compositions ((87Sr/86Sr)i = 0.705–0.706; εNd = −4.9 to −5.2) indicate an enriched lithospheric mantle source. Combined with regional tectonic data, the Tongcheng ultrapotassic rocks were generated in an extensional environment, which were caused by the upwelling of asthenospheric mantle. Subduction of the palaeo‐Pacific Plate in Early Cretaceous resulted in large‐scale lithospheric thinning in the eastern North China Craton (NCC), which may have also occurred in the western part of the NCC, but the scale of thinning was smaller compared with that of the eastern NCC.

The Qinling‐Dabie‐Sulu orogen is the eastern part of the Central China Orogenic Belt. Looking back on previous studies of the sedimentary record we systematically compiled the dataset of detrital zircon U–Pb ages and Hf isotopes for this orogenic belt. The dataset incorporates a comprehensive compilation of 32,449 detrital zircon U–Pb ages and 979 Hf isotopes. The findings demonstrate that distinct tectonic units within the orogenic belt exhibit unique tectonic evolution histories during various geological epochs. This dataset can be used to constrain the tectonic framework and orogenic evolution including ocean subduction, continental collision and orogen exhumation. It can be integrated with other geological datasets to improve our understanding of the Central Orogenic Belt in China, and possibly plate tectonics globally.
