“…[10] It was reported that NW-SE trending extensional stress field (marked as big gray arrows in Figure 1) dominate rifts during Late Mesozoic to Early Cenozoic [e.g., Ren et al, 2002;Zhao and Zheng, 2005] in the Eastern Block. Our results show that the fast polarization directions trending NW-SE agree with the orientation of extensional structures in this region.…”

A compilation of shear wave splitting measurements in the North China Craton (NCC) is presented to investigate the upper mantle anisotropy beneath the region. By applying the method of Silver and Chan (1991), the splitting parameters of fast polarization direction and delay time are determined from SKS waveforms for 38 broadband stations. The results reveal the presence of small to large seismic anisotropy in the mantle beneath the NCC. The most striking result is the distinct difference of fast polarization directions between the Eastern Block (EB) and the Central Zone (CZ) of the NCC. The fast polarization directions trend SE beneath the EB, which implies that northwestward mantle flow has played a significant role in the reactivating of the EB during Late Mesozoic to Early Cenozoic, and the boundary between the CZ and the EB was possibly a west limit where the mantle flow was deflected. However, a collision event occurred in Early Proterozoic was also a possible cause for the anisotropy of the lithosphere beneath the CZ, depending on the craton lithosphere beneath the region had not been completely reformed by later tectonic activities.

“…However, extensive petroleum exploration in the Subei-South Yellow Sea Basin (Fig. 1) to the north of the modern delta has revealed the stratigraphy of Late Cretaceous-Cenozoic sedimentation, indicating that large fluvial systems must have been feeding the basin since a much earlier time (6). In addition, U-Pb dating of zircons from the modern delta region shows that a river indistinguishable from the modern stream was supplying sediments to that area before 3.2 Ma (7).…”

The development of fluvial systems in East Asia is closely linked to the evolving topography following India-Eurasia collision. Despite this, the age of the Yangtze River system has been strongly debated, with estimates ranging from 40 to 45 Ma, to a more recent initiation around 2 Ma. Here, we present 40 Ar/ 39 Ar ages from basalts interbedded with fluvial sediments from the lower reaches of the Yangtze together with detrital zircon U-Pb ages from sand grains within these sediments. We show that a river containing sediments indistinguishable from the modern river was established before ∼23 Ma. We argue that the connection through the Three Gorges must postdate 36.5 Ma because of evaporite and lacustrine sedimentation in the Jianghan Basin before that time. We propose that the present Yangtze River system formed in response to regional extension throughout eastern China, synchronous with the start of strike-slip tectonism and surface uplift in eastern Tibet and fed by strengthened rains caused by the newly intensified summer monsoon.Asian monsoon | drainage capture | provenance | Subei Basin | Yangtze gravel

“…Lastly, the D5 Cretaceous extensional event is already well known since Early Cretaceous syn-kinematic plutons are coeval with ductile normal faulting and Late Cretaceous halfgrabens are widespread throughout eastern China (Faure et al, 1996;Faure et al, 1999;Lin et al, 2000 andRen et al, 2002). A general discussion of such a continental-scale phenomenon is beyond the scope of this paper.…”

The Feidong-Zhangbaling Massif is located between the Dabieshan and Sulu areas along the Tan-Lu fault in eastern China. Five tectonic-metamorphic events are distinguished there. The earliest deformation (D1) corresponds to a southward compression that occurred during subduction of the South China Block below the North China Block. Top-to-the-south shearing is coeval with Late Permian-Early Triassic blueschist facies metamorphism, and possibly with the development of south-verging recumbent folds in the Neoproterozoic-Paleozoic sedimentary cover of the South China foreland. The main ductile deformation (D2) is an extensional one, characterized by top-to-the-north shearing, coeval with the early stage of exhumation of the high-pressure rocks. A top-to-the-NW ductile shearing, and microfolds overturned to the northwest, belong to a second deformational phase of exhumation (D3) which is distinct from the main event (D2). Previous 40 Ar-39 Ar mica dates ranging between 245 and 212 Ma suggest Late Permian-Early Triassic ages for the D1 to D3 events. The D4 event produced NE-SW trending folds in the sedimentary cover interpreted as gravity collapse structures. A Late Cretaceous brittle extensional event (D5) controls the opening and infill of continental half-grabens. In the study area, the Tan-Lu fault is a Cretaceous brittle normal fault. The lack of ductile deformation presented along the Tan-Lu fault suggests that it did not play a significant role in the exhumation of high-pressure metamorphic rocks.
