Tectonics of the Qinling (Central China): tectonostratigraphy, geochronology, and deformation history

Petrogenesis of the early Cretaceous Funiushan granites on the southern margin of the North China Craton: Implications for the Mesozoic geological evolution

“…1A). The belt underwent multi-stage tectono-magmatic thermal events from Archaean-Proterozoic to Mesozoic (Zhang et al, 2001;Ratschbacher et al, 2003;Dong et al, 2011;Wu and Zheng, 2013;Zheng et al, 2013).…”

Provenance and tectonic-paleogeographic evolution: Constraints from detrital zircon U–Pb ages of Late Triassic-Early Jurassic deposits in the northern Sichuan basin, central China

“…On the basis of paleomagnetism (Enkin et al, 1992;Zhao and Coe, 1987;Zhu et al, 1998) and geochronology (Dong et al, 2011 and references therein;Yin and Nie, 1993), the first collision was considered to have occurred diachronously, starting from the east in Shandong and northern Korea in late Early Permian and progressing to the west in Qinling-Dabie in the latest Triassic to earliest Jurassic. However, the time when the amalgamation between the NCB and SCB began and ended along the Qinling-Dabie-Sulu orogen has been disputed for many years Liu et al, 2013;Ratschbacher et al, 2003). For example, the accretion of the SCB to NCB was suggested to occur along the Shangdan suture zone in Silurian-Devonian following the fact that the South Qinling belt (SQB) began to receive sediments from the North Qinling in middle Paleozoic (Gao et al, 1995;Kröener et al, 1993;Zhang et al, 1997).…”

“…In contrast, paleomagnetic data (Enkin et al, 1992;Yang et al, 1992), together with ultrahigh-pressure metamorphism at 230 Ma in the easternmost Qinling-Dabie belt (Ames et al, 1996;Hacker et al, 1998;Okay et al, 1993) blocks. The discovery of the Mianlue suture zone between the South Qinling and SCB was invoked to reconcile the above inconsistence and draw a conclusion that it is the Late Triassic collision between the SCB and South Qinling that finally resulted in the accretion of the SCB to NCB Zhang, 1999, 2000;Ratschbacher et al, 2003). The end time of their collision is poorly constrained partly due to the lack of studies on the Jurassic and Cretaceous strata.…”

“…The Qinling orogen preserves a record of late mid-Proterozoic to Cenozoic tectonism in central China (Ratschbacher et al, 2003). Despite knowledge of the Cenozoic uplift of the Qinling Mountains since the work of Young et al (1943), in their discussion Guo et al indicate intensive uplift near the Tibetan Plateau during the late Miocene (Molnar, 2005) but they do not accept the idea of Miocene reactivation.…”
