“…A denudation event since late Cenozoic was also observed in Reid et al (2005) thermal history modeling of apatite fission track. The authors eliminated the possibility of late Cenozoic denudation as it is not consistent with the lower crustal flow models in which no large-scale surface uplifting in eastern Tibet is required.…”

“…The Yidun island arc was collided with the Songpan-Garzê fold belt along the Garzê-Litang suture [10] ; a thrust system has developed along the suture zone. The northern end of Garzê-Litang thrust system is cut by the Garzê strike-slip fault (also called Yushu-Garzê strikeslip fault).…”

“…Based on K-feldspar 40 Ar/ 39 Ar multiple diffusion domain (MDD) in combination with apatite fission track thermal history, Reid et al concluded that east Tibet including Yidun island arc experienced rapid uplift and denudation during late Triassic and early Cretaceous rather than Cenozoic [10] . A denudation event since late Cenozoic was also observed in Reid et al (2005) thermal history modeling of apatite fission track.…”

“…Roger et al [9] suggested that the north deformational margin of the Tibetan Plateau was located along the Jinsha Jiang suture during 50-40 Ma, which was earlier than those of other areas in Himalayan and Tibetan Plateau [9] . 40 Ar/ 39 Ar thermochronology on feldspars from granites sampled from the west and east Garzê-Litang thrust indicated that granites in this portion of eastern Tibet cooled below ~200℃ before Eocene, and thermal history modeling further showed that the apatite fission track passed partial annealing zone during Cenozoic [10] . 40 Ar/ 39 Ar step-heating experiments on muscovite, biotite and K-feldspar have suggested that two rapid cooling events occurred in Xianshui He fault zone during 12-10 Ma and 5-3.5 Ma [11] .…”

Granites sampled from Garzê-Litang thrust, Longmen Shan thrust, Garzê and Litang strike-slip faults in the eastern Tibetan Plateau have been analyzed with apatite fission track thermochronological method in this study. The measured fission track apparent ages, combined with the simulated annealing modeling of the thermal history, have been used to reconstruct the thermal evolutionary histories of the samples and interpret the active history of the thrusts and faults in these areas. Thermal history modeling shows that earlier tectonic cooling occurred in the Garzê-Litang thrust in Miocene (~20-16 Ma) whereas the later cooling occurred mainly in the Longmen Shan thrust since ~5 Ma. Our study suggests that the margin of eastern Tibetan Plateau was extended by stages: through strike-slip faults deformations and related thrusts, the upper crust formed the Garzê-Litang margin in the Miocene epoch and then moved to the Longmen Shan margin since ~5 Ma. During this process, the deformations of different phases in the eastern Tibetan Plateau were absorbed by the thrusts within them and consequently the tectonic events of long-distance slip and extrusion up to hundreds of kilometers have not been found.

“…The Yidun Arc, which occupies a large part of QY, is composed of Paleozoic melange and Permian-Tertiary shales and sandstones that yield upper Paleozoic to Proterozoic zircon ages (Wang et al 2000;Reid et al 2005b;Deng et al 2014); these ages are consistent with medium ESR signal intensities of~8.…”

The Asian summer monsoon exerts a strong influence on the hydrologic cycle in East Asia. Moreover, the distribution of heavy precipitation in the Yangtze River basin, which covers a large area of South China, is sensitive to changes in monsoon intensity. Thus, the paleo-distribution of heavy precipitation in the Yangtze basin is key in reconstructing the paleo-monsoon intensity. In this study, we established proxies for distinguishing sediments from the northwestern and southeastern parts of the Yangtze River basin, with the goal of using them to reconstruct the paleo-distribution of heavy precipitation in the basin based on changes in the provenance of detrital sediments, as determined using sediment records at the river mouth. The proxies included the electron spin resonance (ESR) signal intensity and the crystallinity index (CI) of quartz in modern riverbed sediments along the mainstream and tributaries of the Yangtze River. The data revealed that the fine-silt fraction of the sediments (which represents suspended particulate matter, SPM) from each major tributary can be distinguished on the basis of ESR signal intensity and CI values. The values for each tributary reflect the age and type of bedrock in the tributary basin and show distinct regional variations according to the distribution of geological blocks within the Yangtze basin. In addition, the analyzed ESR signal intensity and CI values of the fine-silt fraction of riverbed sediments below mainstream-tributary junctions agree well with values calculated according to a simple mixing model of SPM discharged from the tributaries and the mainstream.

A thermochronological perspective on the morphotectonic evolution of the southeastern Tibetan Plateau

A large part of the southeastern Tibetan Plateau (TP) is characterized by low-relief surfaces at high elevations (>3.5 km). The origin of these landscapes and their geodynamic implications with regard to evolution of the southeastern TP has been the subject of considerable debate. Focusing on this topic, this study utilizes fission track and (U-Th)/He thermochronology to reconstruct the thermal history of the Late Triassic Daocheng granite, on which a low-relief high-elevation landscape has developed. Results suggest that the plateau surface experienced widespread Late Jurassic to Early Cretaceous cooling (at a rate of~1-2°C/Ma), followed by minimal regional cooling (~0.3°C/Ma) and Early Miocene enhanced cooling (~2-3°C/Ma) along deep valleys at the southern edge of the landscape. Given the subdued Late Jurassic to Early Cretaceous crustal deformation in the study area, we relate the coeval cooling to crustal refrigeration and exhumation triggered by northward subduction of the Meso-Tethys Ocean along the Bangong suture. Subsequent Late Cretaceous to Cenozoic minimal cooling supports arguments for the formation of a low-elevation landform prior to uplift of the southeastern TP. The enhanced cooling commenced at the Early Miocene (~15-22 Ma) along deep valleys and heralded the onset of river incision and surface uplift of the southeastern TP. This finding does not support previous proposals claiming that high elevations of the southeastern TP were formed in Late Miocene time resulting from lower crustal flow but rather supports a model highlighting continental subduction and extrusion along the large Tanggula-Yushu-Batang-Red River fault system.
