Permian tectonic evolution of the southwestern Ordos Basin, North China: Integrating constraints from sandstone petrology and detrital zircon geochronology

The Late Palaeozoic dynamic setting of the Ordos Basin in the southwestern North China Craton (SW‐NCC) is poorly constrained due to limited understanding on the source‐to‐sink relation. This study presents integrated provenance clues from the Permian strata in the southwestern Ordos Basin to trace the sources and to discuss the tectonic setting of the basin in the SW‐NCC. The reconstructed palaeocurrent directions of these Permian sediments generally point to the northeast and suggest the dominant sedimentary influx from the southwest. Modal composition analysis shows the Permian deposits have an overwhelming derivation from mixed sources containing orogeny, continental block, and magmatic arc. Zircons from the lower section yield major age clusters of ~300–270 Ma and ~2,500–1,700 Ma. While, zircon age spectra for the upper section are marked by the abundance of ~1,000–800 Ma and ~500–400 Ma ages, and the lack of Permian populations. Sources of the lower section were interpreted to be the arc terrane along the southern border of SW‐NCC, in contrast, sources of the upper part were attributed to the Central Qilian Block. Zircons of ~300–270 Ma indicate significant magmatic activities in a rapidly uplifting continental arc, yielding an additional clue for the subduction and the existence of the Mianlue Ocean in the northeastern Palaeo‐Tethys. The changes in provenance and depositional rate at the Middle Permian indicate the rapid subsidence along with the intensive uplift of the continental basement in the SW‐NCC. These signatures likely infer that the back‐arc basin may have evolved into a compressional setting at that time.

“…The Ordovician tectonics of the North China Craton (NCC) changed significantly from a relatively stable tectonic regime in a passive continental margin setting in the Cambrian to tectonics characterized by widespread subduction/collision‐related magmatism and metamorphism in the peripheral CCOB (Dong, Genser, Neubauer, et al, 2011; Dong & Santosh, 2016; Song et al, 2013, 2009) and CAOB (Eizenhöfer & Zhao, 2018; Eizenhöfer, Zhao, Sun, et al, 2015; Eizenhöfer, Zhao, Zhang, et al, 2015; Liu et al, 2016; Xia et al, 2012; Xiao et al, 2003, 2015, 2009; Zhang, Zhao, et al, 2016; Zhang et al, 2014) and intensive basin inversion followed by prolonged uplift and denudation in the interior of the NCC (Chen & Liu, 1995, 1999; Li, Chen, et al, 2012). The tectonic mechanism for the evolution of the basin in the western NCC (W‐NCC) and the tectonic evolution of the surrounding orogens during the Ordovician are intensively debated topics (Yuan & Yang, 2014, 2015; Zhang et al, 2018; Zhang, Li, Li, & Ma, 2009; Zhang, Li, Liu, & Feng, 2011; Zhang, Zhang, & Zhao, 2016; Zhang, Zhang, Xiao, Wang, & Zhang, 2015), leading to a redefinition of the Phanerozoic tectonic affinity between the Ordos Block and the Alxa Terrane (Figure 1). Recently, an increasing number of researchers have asserted that the Alxa Terrane was not an extension of the W‐NCC until the Ordovician, and have inferred that various plate boundaries exist around the Helanshan Tectonic Belt (HTB) of the North‐western Ordos Terrane (NOT; Figure 2), such as around the Bayanwulan Fault (Dan et al, 2016; Gong et al, 2015; Zhang, Gong, Yu, Li, & Hou, 2013), the eastern and western sides of the HTB (Li, Zhang, & Qu, 2012; Wang, Zhou, et al, 2016; Yuan & Yang, 2014, 2015; Zhang et al, 2011; Zhang, Li, Xiao, Wang, & Qi, 2013; Zhang, Zhang, & Zhao, 2016; Zhang, Zhang, et al, 2015) or the Chedao–Aselang Fault (Xu et al, 2015).…”

The western North China Craton (W-NCC) comprises the Alxa Terrane in the west and the Ordos Block in the east; they are separated by the Helanshan Tectonic Belt (HTB). There is an extensive debate regarding the significant Ordovician tectonic setting of the W-NCC. Most paleogeographic reconstructions emphasized the formation and rapid subsidence of an aulacogen along the HTB during the Middle-Late Ordovician, whereas paleomagnetic and geochronologic results suggested that the Alxa Terrane and the Ordos Block were independent blocks separated by the HTB. In this study, stratigraphic and geochronologic methods were used to constrain the Ordovician tectonic processes of the W-NCC. Stratigraphic correlations show that the Early Ordovician strata comprise ~500-m-thick tidal flat and lagoon carbonate successions with a progressive eastward onlap, featuring a west-deepening shallow-water carbonate shelf. In contrast, the Late Ordovician strata are composed of ~3,000-m-thick abyssal turbidites in the west and ~400-m-thick shallow-water carbonates in the east, defining an eastward-tapering basin architecture. Early Ordovician detrital zircons with ages of ~2,800-1,700 Ma were derived from the Ordos Block; the Late Ordovician turbidites were sourced from the western Alxa Terrane, based on zircon ages clustered at ~1,000-900 Ma. The petrographic modal composition and zircon age distribution imply a provenance shift from a stable craton to a recycled orogen in the Middle Ordovician. These shifts define a tectonic conversion from a passive continental margin to a foreland basin at ~467 Ma, resulting in the eastward progradation of the turbidite wedge around the HTB, the eastward backstepping of the carbonate platform in the east and the eastward expansion of orogenic thrusting in the western Alxa Terrane. This tectono-sedimentary shift coincided with the advancing subduction of the southern Paleo-Asian Ocean beneath the Alxa Terrane, generating the western Alxa continental arc and the paired retro-arc foredeep in the east under a compressional tectonic regime.

The Late Ordovician Pingliang Formation in the Guanzhuang section, located in the south‐western Ordos Basin, North China, contains several K‐bentonite layers, which are important for understanding the tectonic evolution of the south‐western Ordos Basin. This study provides new geochemical and SIMS U–Pb geochronological data for the K‐bentonites to establish the Ordovician high‐resolution chronostratigraphic framework for the Ordos Basin and to provide temporal constraints of major volcanic–magmatic activity. K‐bentonites in the succession yield U–Pb zircon ages of 457.6 ± 3.8 Ma and 454.8 ± 3.8 Ma (2σ analytical uncertainty), showing a depositional age in the Sandbian Stage (Late Ordovician). The result is consistent with the biostratigraphic and astrochronologic framework, achieving the intercalibration of different dating methods. The discrimination diagrams of whole‐rock Na2O+K2O against SiO2 and Zr/TiO2 against Nb/Y and Th/Yb against Nb/Yb and Th‐Hf‐Ta indicate that the K‐bentonites have obvious arc affinities. Based on the geological background, we conclude that the K‐bentonites in the south‐western Ordos Basin were mainly deposited during the development of the North Qilian‐North Qinling volcanic arc in the Sandbian.
