“…This section consists mostly of bioturbated siltstone with carbonate nodules. However, there are intervals of lenticular sandstone and conglomerate with limestone gravels [14,26]. The overall lithologic similarity with the underlying Badong Formation, widely thought to be tidal in origin, possibly suggests a similar depositional setting.…”

“…The Late Triassic-Middle Jurassic foreland basin was developed along the Dangyang-Daye area, and was involved in deformation at the later stage (J 3 -K 1 ) with a southern frontal thrust fault [28] (Figure 2(a)). The Xiangfan-Guangji fault, as a main controlling fault in the NYFB, developed as a thrust during collision [14,25,26], and acted as a sinistral transtensional fault during Cretaceous exhumation of the HP rocks [29]. Field observations indicate that at an earlier stage this fault behaved as a south-directed flat thrust and tight fold of Cambrian-Silurian strata which were overlapped by HP metamorphic rocks.…”

“…The Xiangfan-Guangji fault locally buries older deformation including the Mianlue suture [14,25,26]. The middle part of the NYFB is also unconformably overlapped by Cretaceous to early Tertiary deposits of the Jianghan basin, formed during later rifting.…”

“…The thrust belt is narrow to the west along a basement high, the Huangling dome, and pinches out to the east at Wuxue City [14]. The NYFB thrust southwards and the Jiangnan fold and thrust belt (JNFB) expanded northwestwards, the two belts joining together and overlapping each other [26]. Based on the deep seismic profile across the Dabie orogen, the Xiangfan-Guangji fault can be traced from the surface to the Moho in a zone dipping north, the Dabie metamorphic terrane thrusts southward, and both of JNFB and NYFB converge and central-vergently thrust [25,27].…”

The Dabie orogen underwent deep continental subduction, rapid exhumation, and the huge amount of erosion during the Mesozoic. Its tectonic evolution, especially how its evolution was recorded by sedimentary basins at the flanks of the Dabie orogen is one of the most important issues of the world's attention. These years, newly studies of basin sedimentology, combined with structural geology, have shown a fundamental progress. The overall distribution of different basin types in the orogen indicates that shortening and thrusting at the margins of the orogen from the Late Triassic to the Early Cretaceous controlled the foreland basins, and extension, doming and rifting were initiated in the core of the orogen from the Jurassic to the Early Cretaceous and were expanded to the whole orogen after the Late Cretaceous. Therefore, The Dabie orogen records gradual transition from overall shortening and thrusting to dominantly extension and rift basin formation expanded from its core to its margins, although these shortening and extension overlapped in time from the Jurassic through Early Cretaceous at crustal levels. The unroofing ages of the ultra-high pressure (UHP) metamorphic rocks in the Dabie orogen change from Early Jurassic to Late Jurassic westward. The depth of exhumation increases eastwards. The sediment sources for the Hefei basin are mostly composed of the deeply exhumed, axial Dabie metamorphic complex, and the sediment sources for the Middle Yangtze basin are mostly from cover strata in the southern orogen and related strata with subjacent (i.e. subsequently overthrusted) Mianlue suture belt. Geodynamic analysis represents that continental collision between the North China Block and the South China Block along the Shangdan and Mianlue sutures, subsequently northwestward progradation of the Jiangnan fold and thrust belt, and the underthrusting of the North China Block along the Northern Boundary Fault of Qinling Range led to crustal thickening, gravitational spreading and balanced rebound of the resultant thick crustal welt, and multi-episodic exhumation of the HP/UHP metamorphic rocks. The future studies by the methods of tracing the Dabie orogeny through deposition in the marginal basins should focus on eastward extension of the Mianlue suture, thrust and overlap of the Dabie HP/UHP metamorphic block on different lithotectonic zones and basins along the northern South China Block, the structural framework of the source area of the basins in the syn-depositional stage, the basin lateral extension, huge amount of erosion and sediment transportation from the Dabie blanket and basement rocks, and recovery of subducted and removed structural units within the Dabie orogen, etc.Dabie orogen, sedimentary basin, evolution of basin/mountain system, HP/UHP metamorphic rocks, provenance analysis, exhumation process, depositional paleogeography

Oblique closure of the northeastern Paleo-Tethys in central China

et al. 2015

A branch of the Paleo-Tethys Ocean once separated the north China plate from the south China plate. However, the mode of closure of the northeastern Paleo-Tethys Ocean during the Late Paleozoic to Early Mesozoic has been debated. One reason for this debate is that the collisional suture zone was later buried by large-scale thrust faults in the southern Qinling-Dabieshan orogen, which made it difficult to reconstruct the amalgamation of the supercontinent in central China. New regional geologic mapping provides stratigraphic and structural constraints on the mechanism of this ocean closure. Our results indicate that dextral transpressional suturing in the southern Qinling-Dabieshan foreland fold-thrust belt resulted in the formation of the northern Yangtze foreland basin, where the stratigraphy precisely shows the time-transgressive closure of the ocean, and the orogenic sediments shed over 1000 km westward from eastern China to the closing Paleo-Tethys. Therefore, we propose an oblique subduction model to describe the closure of the Paleo-Tethys Ocean. Our findings suggest that prolonged slab pull during the oblique subduction of the oceanic plate continued to drive deep continental subduction, thereby forming high-and ultrahigh-pressure metamorphic rocks and leading to sustained ocean closure.
