The formation and evolution of the foreland basin in the south of the Dabie Orogen are both closely related to the uplift of the orogenic belt. However, the Late Triassic paleoenvironment and the provenance of the sediments in the foreland basin remain controversial. Nine samples from the Upper Triassic Puqi Group of the foreland basin were analysed for whole‐rock major and trace elements and three sandstone samples were selected for zircon dating by U–Pb laser ablation inductively coupled plasma mass spectrometry. The concentrations of some major (e.g., CaO and Na2O) and trace (e.g., Rb, Sr and Ba) elements varied over a large range and showed different degrees of depletion. A series of major and trace element indicators, as well as the patterns of the rare earth elements, suggested derivation from felsic igneous rocks. The Late Triassic experienced fluctuations between cold warm climates, as indicated by the chemical weathering index ranging from 51.33 to 88.65. The CaO/(FeO + CaO), Rb/Sr and Ba/K ratios indicated that the paleosalinity changed from high to low. The Fe2O3/FeO, U/Th, V/Cr and Ni/Co ratios indicated an oxidizing sedimentary environment. The cathodoluminescence images, Th/U ratios and rare earth elements patterns of the detrital zircons all indicated a magmatic origin. Three samples showed significant peak ages of 224, 440, 748, 1870 and 2492 Ma, corresponding to the development of the Dabie Orogen. Our comprehensive analyses suggest that the Upper Triassic Puqi Group was formed by deposition during continental–continental collision. The Dabie Orogen was exhumed in the Late Triassic and supplied detrital sediments to the foreland basin.

“…Regionally, extensional structures, such as MCC type extensional gneissic domes, detachment faults, and extensionrelated basins, are widespread from Trans-Baikal to SCB, over more than 3,000 km along the eastern Asian continent (Figure 14) (Huang et al, 2021;Lin et al, 2015;Zhou et al, 2012). These extensional structures exhibit a consistent NW-SE oriented maximum stretching direction.…”

A dominantly NW-SE directed extensional tectonics in the Early Cretaceous significantly reworked the Late Permian-Triassic orogenic framework of the Dabie orogenic belt. The North Dabie complex (NDC) is the principal domain recording this tectonic event. However, the precise structure-kinematic architectures, particularly those observed in the ductile regime, along with the respective time scales for different extensional stages, have not been adequately established. This significantly impedes our comprehensive understanding of the extensional style and deformation history in the North Dabie complex. To better address these issues, we conducted a systematic structural study and LA-ICP-MS zircon U-Pb dating of the pre-, syn-, and post-kinematic intrusions and syn-kinematically metamorphosed high-grade gneisses/migmatites of the NDC. Our results demonstrate that the extensional deformation in the NDC may initiate at ca. 144 Ma, which is characterized by a pervasive NW-SE oriented coaxial plastic flow in the ductile regime of the middle-lower crust. A large-scale detachment processing zone subsequently started activating at ca. 140 Ma at the upper-middle level of the middle crust, and concentratedly accommodated the extensional strain by top-to-NW ductile shearing. Locally, there was uprising of sub-magmatic flow in the atatexite-diatexite from the deeper lower crust taking place in the manner of top-to-outward shearing as early as ca. 137 Ma. This composite process of extension manifests vertical strain partitioning across the ductile middle-lower crusts and progressive strain localization during the lithospheric thinning. The NW-SE orientation dominated extensional tectonics was strongly driven by the westward subduction of the Paleo-Pacific oceanic plate during the Late Mesozoic.

“…The position of the Shangdan suture in the Dabie Orogen remains controversial (Liu et al, 2013;Wu and Zheng, 2013;Huang et al, 2016Huang et al, , 2021. And thus, whether the Huwan complex is affiliated to the Yangtze Block or the North China Block is still relatively uncertain (Wu et al, 2009;Liu et al, 2011;Peters et al, 2013;Wu and Zheng, 2013).…”

To better understand the Precambrian tectonic evolution of the Dabie Orogen in the northern margin of Yangtze Block, we present geochronological data for metasedimentary and metavolcanic rocks in the Huwan Complex. A total of 385 detrital zircon LA‐ICP‐MS analyses for metasedimentary rocks yielded three 207Pb/206Pb age populations: 1.50–1.80 Ga, 1.81–1.87 Ga and 1.93–2.0 Ga, providing a maximum depositional timing of ca.1.50 Ga; while metafelsic volcanic gneisses yielded protolith U‐Pb ages of 1893 ± 54 Ma. The peak ages are remarkably consistent with the tectonothermal events that occurred in the northern Yangtze Block, indicating the presence of Paleo‐ to Meso‐proterozoic magmatism in the Dabie Orogen. The age range of 1.93–2.0 Ga correlates with the Paleoproterozoic collision; the age range of 1.81–1.87 Ga coincides with the period of the post‐orogenic extension; and the age range of 1.50–1.80 Ga Ma is interpreted to associate with an extensional regime. Zircon cores with age of 1732–1965 Ma have εHf(t) values ranging from ‐11.70 to ‐2.47, indicating that juvenile crust involved in their magma sources. Owing to the similar age spectra, we proposed that the nucleus of the Dabie Orogen was close to the Yangtze Block since the Paleoproterozoic. The Huwan Complex has an intimate affiliation to the Yangtze Block. The Huwan complex was not only experienced the Paleo‐Tethys ocean subduction and collision, but also recorded Paleo‐ to Mesoproterozoic tectono‐magmatic events in the Dabie Orogen.
