“…The Huangling Anticline and Qinling Shan mainly comprise granite outcrops, whereas metamorphic rocks constitute the main body of the Dabie Shan, which further rules out they non-existing provenance with Cretaceous strata analysed in this study. Zircon U-Pb dating and heavy mineral provenance tracing indicated that rivers in the western Huangling Anticline flowed westward into the Sichuan Basin during the Cretaceous (Li et al, 2018;Deng et al, 2018;Wang et al, 2021a;Zhao et al, 2021a). Therefore, we argue that there was no provenance connection between the Mesozoic strata in the western Jianghan Basin and the Yangtze River during the Cretaceous.…”

“…Integrated with detrital zircon U-Pb (Chen et al, 2017;Feng et al, 2021;Wang et al, 2021a), heavy mineral (He et al, 2021), and K-feldspar Pb isotope (Zhang et al, 2021a) data, previous studies suggest that the upper reaches of the Yangtze River were separated from the Red River system at ~36-35 Ma. Furthermore, based on apatite fission-track and (U-Th)/He low-temperature thermochronology data from the Huangling Anticline, an enhanced cooling event occurred at 40 Ma.…”

“…Detrital zircon U-Pb dating (Deng et al, 2018;Li et al, 2018;Wang et al, 2021a) and the provenance of heavy mineral assemblages (Deng et al, 2018) indicate that the rivers derived from the western parts of the Huangling Anticline flowed into the Sichuan Basin from east to west during the Cretaceous (Figure 1B). This means that no large rivers flowed through the Sichuan and Jianghan basins at that time.…”

“…Kernel density estimation (KDE) plots were generated using the DetritalPy code (Sharman et al., 2018), while metric multiple‐dimensional scaling (MDS) and Shepard plots for samples were calculated using the DZmds (Saylor et al., 2018). A high‐quality MDS plot will usually exhibit a linear relationship and low‐stress values less than 0.2 in the Shepard plot (Kruskal, 1964; Vermeesch, 2013), meaning that distances displayed on the MDS plot consistently scale to the dissimilarity metric (Rinke‐Hardekopf et al., 2021; Wang et al., 2021). The detrital zircon U–Pb age unmixing model (DZmix) was also used to quantify the relative contribution of potential source areas (Sundell & Saylor, 2017).…”

The submarine fan with a narrow shelf is usually reactive to environmental signal propagation; however, source‐to‐sink functioning can be further complicated by several allogenic forcings. Here, we document the high‐frequency provenance variations and different sediment delivery models recorded in the late Triassic Zhuoni fan developed in the northeastern Paleo‐Tethys Ocean, mainly based on process‐based sedimentological and provenance study of the Panyuan section in the West Qinling area in the northeastern margin of Tibetan Plateau. High‐, low‐density turbidites, hybrid event beds and hyperpycnites are distributed in the lobe‐dominated submarine fan succession. Field sedimentological evidence from surrounding outcrops suggests that shelf‐edge failure was the main cause of most high‐ and low‐density turbidites with the overall absence of submarine slides or slumps, whereas the narrow shelf configuration together with late Triassic humid pulses is favourable for the occurrence of flood‐related hyperpycnites in the Zhuoni fan. Detrital zircon grains (N = 6; n = 123–272) generally have Palaeozoic‐Mesozoic ages (ca. 350–250 Ma and 500–400 Ma) and Neoarchean‐Paleoproterozoic ages (ca. 2100–1750 Ma and 2600–2400 Ma), but they can be further categized into three age groups due to different proportions of Precambrian age populations. The results demonstrate that the potential source areas may include the South and North Qinling Orogenic Belt, Qilian Orogenic Belt, different segments of North China Craton and the tectonic junction area between the Qinling and Qilian Orogenic Belts. The temporal changes in provenance signals, which are reflected by both the detrital zircon age spectra and heavy mineral assemblages, indicate different contributions of those sources in response to sea‐level fluctuation. It could thus give rise to temporal variations between reactive and buffered source‐to‐sink sediment delivery models of the Zhuoni fan, despite the overall narrow shelf configuration. The development of the lowstand Zhuoni fan was directly related to extrabasinal hyperpycnal delivery from the river mouth and its high‐frequency provenance variability recorded different efficiencies of signal transfer through the onshore catchment with significantly influence of temporal storage, fluvial rejuvenation or even regional climate variability. The highstand submarine fan was thought to be formed by shelf‐edge failure with sediment buffering in the shelf region, which was associated with a strong magnitude of provenance mixing. Our work provides a new perspective for deciphering the different origins of deep‐water sediment delivery in response to high‐frequency sea‐level and climate changes.

“…Numerous studies have been conducted on the tectonic uplift history of the eastern Tibetan Plateau in the past decades. However, most of the previous studies have only been concentrated on tectonic uplift history studies on the early Late Mesozoic (Late Triassic-early Jurassic) and Cenozoic Tian et al, 2013, 2014aTan et al, 2017;Shen et al, 2019;Tan et al, 2019;Yang et al, 2019), while the tectonic evolution history of the Late Mesozoic (Middle and Late Jurassic-Cretaceous), especially the Cretaceous period, remains unclear (Xue et al, 2017;Wang et al, 2021), hindering our understanding of the early formation and evolution of the Tibetan Plateau.…”

Reconstruction of the Cretaceous tectonic evolution of the eastern margin of the Tibetan Plateau is of great significance to understanding the formation and early evolution of the Tibetan Plateau. The thick late Mesozoic sedimentary sequence in the Western Sichuan Basin may record the evolution of the basin itself and the tectonic uplift history of the eastern margin of the Tibetan Plateau during the Cretaceous period. Here we provide new multi-proxy provenance data from conglomerate clast populations, sandstone petrography, heavy mineral assemblages, U-Pb dating of detrital zircon, paleocurrent data, and detrital garnet geochemistry from the Cretaceous clastic units in the southwest corner of Sichuan Basin. Our analysis reveals two distinct changes in sediment provenance recorded in the Cretaceous strata at the southwest corner of the Sichuan Basin. The first significant change of detrital provenance was identified in the mid-Cretaceous Jiaguan Formation. Metamorphic rocks and volcanic rocks clast, as well as feldspar and mica, increased significantly, a heavy mineral assemblage dominated by hematite–limonite and ilmenite with high ATi and RuZi and low ZTR values, predominantly type Bi garnet and mostly 164 Ma, 207 Ma, 440 Ma, 780 Ma–824 Ma, and 1840 Ma detrital zircon ages, interpreted to be sourced from the Songpan-Ganzi fold belt and Longmenshan orogenic belt. The second shift, in the Guankou Formation, is marked by a low compositional maturity, a distinct increase in fossiliferous carbonate clasts and high GZi index with type Bii garnet, and Triassic zircon ages, indicating the exhumation of Longmenshan orogenic belt during the late Cretaceous. These data collectively indicate that the significant surface uplift and rapid denudation of the eastern margin of the Tibetan Plateau were probably initiated in the mid-Cretaceous (∼120 Ma). In conclusion, a detailed hands-on provenance analysis of the clastic sedimentary sequences in the southwest corner of the Sichuan Basin enabled us to determine catchment areas and shifts hitherto unstudied, thus contributing to the exhumation history of the eastern margin of the Tibetan Plateau.
