“…In contrast, the detrital zircon U-Pb age spectra and analysis of heavy minerals and sedimentary facies suggest that a large river connected the western Huangling Massif, Sichuan Basin, Chuxiong Basin, and Lanping Basin during the Cretaceous (Deng et al, 2018;Wang L et al, 2022;Zhao et al, 2022;Wang et al, 2023). The lack of Cretaceous strata in the western part of the Huangling Massif and the interior of the Three Gorges (Chai et al, 2020) may be related to the outflow of the Paleo-Yangtze River. Because of the subduction of the Pacific Plate beneath Li et al, 2014 andChu et al, 2020).…”

In addition, an angle unconformity between the Upper Jurassic and Lower Cretaceous strata occurred in the Zigui (Wang et al, 2012;Chai et al, 2020), Dangyang (Shi et al, 2013), and Jianghan (Shen et al, 2012a) Basins due to the rapid exhumation of the Huangling Massif. These strata are dominated by coarse clastic deposits, indicating a proximate source accumulation.…”

Plate subduction leads to complex exhumation processes on continents. The Huangling Massif lies at the northern margin of the South China Block. Whether the Huangling Massif was exhumed as a watershed of the middle reaches of the Paleo‐Yangtze River during the Mesozoic remains under debate. We examined the exhumation history of the Huangling Massif based on six granite bedrock samples, using apatite fission track (AFT) and apatite and zircon (U–Th)/He (AHe and ZHe) thermochronology. These samples yielded ages of 157–132 Ma (ZHe), 119–106 Ma (AFT), and 114–72 Ma (AHe), respectively. Thermal modeling revealed that three phases of rapid cooling occurred during the Late Jurassic–Early Cretaceous, late Early Cretaceous, and Late Cretaceous. These exhumation processes led to the high topographic relief responsible for the emergence of the Huangling Massif. The integrated of our new data with published sedimentological records suggests that the Huangling Massif might have been the watershed of the middle reaches of the Paleo‐Yangtze River since the Cretaceous. At that time, the rivers flowed westward into the Sichuan Basin and eastward into the Jianghan Basin. The subduction of the Pacific Plate beneath the Asian continent in the Mesozoic deeply influenced the geomorphic evolution of the South China Block.

“…The Qinling orogenic belt, in the north of the Sichuan Basin, is characteristically composed of three plates and two suture zones. Fu (2016) from north to south, the North China plate, the Qinling micro-plate, and the Yangtze plate are separated by the Shangdan suture zone (Xinyang-Shucheng fault) in the north and the Mianlue suture zone (Xiangfan-Guangji Fault) in the south (Zhang et al, 2001;Wang et al, 2019;Cai, 2020). Structurally, the northeastern Sichuan Basin is connected to the Qinling orogenic belt through the Dabashan thrust-fold belt to the north and the Micangshan thrustfold belt to the northwest.…”

This paper discusses the sedimentary environment and source supply in the sedimentary area and their coupling relationship through a detailed description of the deposits from the Ziliujing Formation to Shaximiao Formation of the Lower–Middle Jurassic on the Tieshan section in the Dazhou City, northeastern Sichuan Province, through sedimentary characterization, determination of the paleocurrent direction, analysis of heavy minerals, and detrital zircon U–Pb dating. The results show that the Zhenzhuchong Member is sufficiently supplied with detrital sediments and is dominantly composed of fluvial-delta deposits. The Dongyuemiao Member—the first member of the Lianggaoshan Formation—is dominated by lacustrine deposits, with the detrital supply increased initially in the early Lianggaoshan. The second member of the Lianggaoshan Formation suggests a significant increase in detrital supply, with shrunken lake basin and changed paleocurrent direction. The Shaximiao Formation reveals a complete disappearance of the lake basin in the northern Sichuan Basin. The comprehensive analysis on source supply indicates that the change in source property is apparently coupled with the change in the sedimentary environment, both controlled by orogenesis around the basin. It is inferred from the zircon age distribution that the changes in the sedimentary environment and source supply during the late Ziliujing period and the middle and late Lianggaoshan period resulted from the uplifting of the Micangshan Mountain, Dabashan Mountain, and Qinling Mountain, respectively.

“…Triassic orogenesis in the Qinling Orogenic Belt is not only supported by the evidence of magmatic petrology [6], but also by metamorphic petrology [7][8][9] and sedimentary petrology [10][11][12]. However, there is no consensus on when the Mianlue Ocean began to subduct after the Silurian rifting.…”

Late Paleozoic Tectonic Evolution of the Qinling Orogenic Belt: Constraints of Detrital Zircon U-Pb Ages from the Southern Margin of North China Block

et al. 2022

The tectonic evolution of the Qinling Orogenic Belt in the Late Paleozoic has long been controversial, especially due to the limitation of the Mianlue Ocean subduction time. Basin formation and sedimentary development in the southern North China Block are closely related to the tectonic evolution of the Qinling Orogenic Belt, which is an effective entry point to study basin–mountain interaction. We present new detrital zircon U–Pb data from the Shihezi Formation in the Luonan area in the southern margin of the North China Block. The results show that the bottom sample has two major peaks at 288 Ma and 448 Ma, with weak peaks at 908, 1912 Ma and 2420 Ma. The top sample has one major peak at 297 Ma, with weak peaks at 1933 Ma and 2522 Ma. Combined with the published paleocurrent data and lithofacies paleogeography, the sediments of the bottom sample were sourced from the North Qinling Belt, Inner Mongolia Palaeo-Uplift and the basement of the North China Block. The top sample originated mainly from the Inner Mongolia Palaeo-Uplift and the basement of the North China Block. Comparing the obtained zircon U-Pb ages with the published relevant data in the North China Block, it is found that the provenance area shifted from the Qinling Orogenic Belt to the Inner Mongolia Paleo-Uplift in the Late Carboniferous–Permian, and the Qinling Orogenic Belt could hardly provide provenance for the southern North China Block in the Middle Permian. The uplift of the Qinling Orogenic Belt in the Late Carboniferous may be the continuation of Caledonian orogeny in the Early Paleozoic, whereas the uplift of the Inner Mongolia Palaeo-Uplift is related to the tectonic evolution of the Central Asian Orogenic Belt during the Late Paleozoic. This tectonic transformation occurred when the Qinling Orogenic Belt no longer supplied sediments to the southern North China Block in the Middle Permian, and the Mianlue Ocean subduction did not occur until at least the Late Permian.
