New structural, petrographic, and 40 Ar/ 39 Ar data constrain the kinematics of ASRR (Ailao Shan‐Red River shear zone). In XueLong Shan (XLS), geochronological reveal Triassic, Early Tertiary, Oligo‐Miocene thermal events. The latter event (33–26 Ma) corresponds to cooling during left‐lateral shear. FanSiPan (FSP) range, thrusting SaPa nappe, linked deformation, FSP granite occurred at ≈35 Ma. Rapid resumed 25–29 Ma as a result uplift within transtensive ASRR. DayNuiConVoi (DNCV), foliation...
On the basis of a synthesis tectonic data available on India‐Asia collision, we present first attempt to reconstruct evolution collision zone. Assuming that deformation lithosphere is localized along narrow shear zones and interiors mantle blocks in between remain relatively undeformed, define block contours from fault pattern move back their boundary faults. Along convergent or extensional boundaries, crust assumed shorten stretch coherently. Step‐by‐step, go backward time finally reach...
Using multispectral SPOT images and 1/100,000 topographic data, we present an improved map of the active Red River fault zone between Midu (Yunnan, China) Hanoi (Vietnam). The is composed parallel strands, one which, Yuanjiang was previously undetected. There also appears to be a component extension all along zone. Such increases toward SE, from Yunnan south China sea coast, vector describing motion relative Indochina points within N45°–135°E quadrant. We attempt assess Plio‐Quaternary...
Terra Nova, 22, 290–296, 2010 High wavespeed seismic anomalies in the transition zone and uppermost lower mantle beneath India-Asia collision zone, imaged by body-wave tomography, have been interpreted as subducted fragments of continental material. In this study, we focus on prominent anomaly located India between depths about 450 900 km. By combining location with palaeogeographical positions India, constrain timing subduction event probably related to anomaly. We infer that a large...
Abstract The timing and mechanisms of uplift in southeastern Tibet remain disputed. To address this debate, we conducted structural morphological analyses the Yulong thrust belt; also reconstruct cooling exhumation history Jianchuan basin hanging wall system using inverse thermal modeling apatite fission‐track (U‐Th)/He thermochronology data. Our results provide evidence for 2.3–3.2 km rapid between ~28 ~20 Ma, followed by limited less than 0.2 since then. magnitude is consistent with...
Abstract The Xianshuihe (XSH) fault in eastern Tibet is one of the most active faults China, with next large earthquake likely to occur along its SE part, where splits into three parallel branches: Yalahe, Selaha and Zheduotang (ZDT). Precisely quantifying their slip rates at various timescales essential evaluate regional hazard. Here, we expand our previous work on nearby ZDT Moxi (MX) faults, add observations Yalahe newly discovered Mugecuo South zone. Using tectonic‐geomorphology...

The Litang fault system that crosses the Plateau, a low relief surface at high elevation (~4200–4800 m above sea level) is not affected by regional incision, provides opportunity to study exhumation related tectonics in SE Tibetan Plateau independently of erosion. Combining apatite and zircon fission track with (U-Th)/He thermochronologic data, we constrain cooling history footwall along two transects. Apatite ages range from 4 16 Ma, AHe 2 6 Ma, one age ~99 Ma. These data imply tectonic...
We test the link between large‐scale Asian continent deformations and Indian slab subduction breakoff during convergence by means of three‐dimensional numerical models subducting‐upper plates system. find that buoyant results in reduction velocity comparable to observed motions, yet upper plate deformation remains accommodated a narrow belt along straight margin. Comparable rates are measured when subducting is modeled, although convergent margin deforms curves markedly, with large...
ABSTRACT The incision history of the Three Rivers (Salween, Mekong, and Yangtze) region in Southeast Tibetan Plateau has been linked to both tectonic climatic controls. In this study, we report new apatite (U‐Th)/He fission‐track thermochronology data from >6,000‐m‐high Kawagebo massif, which forms edge high plateau on western flank steepened knickzone reach middle Mekong River valley. Thermal‐history modeling a thermochronological age‐elevation profile shows rapid cooling since ~1.5 Ma...
Abstract How and when the Tibetan plateau developed has long been a puzzling question with implications for current understanding of behaviour continental lithosphere in convergent zones. We present discuss recent data acquired geology geophysics through igneous metamorphic petrology palaeo-altitude estimates. It appears from this research that Tibet initially resulted accretion Gondwana blocks to southern Asian margin during Palaeozoic Mesozoic eras. These successive accretions have...

Abstract Using silicone slabs as a model analogue for lithospheric plates subducting into box of glucose syrup, an the mantle, we explore subduction continental lithosphere in context intercontinental collision. The indenter pushed by piston, reproducing collision, attached to dense oceanic plate, subducts two-thirds depth mantle box. We show that, surprisingly, plate back wall subducts, even if not slab. engine this is weight slab, because slab lighter than but motion which generates...
Abstract Cenozoic climate cooling at the advent of Eocene-Oligocene transition (EOT), ~33.7 Ma ago, was stamped in ocean by a series climatic events albeit impact this global on terrestrial environments is still fragmentary. Yet archival constraints Late Eocene atmospheric circulation are scarce (tropical) monsoonal Asia, and paucity records hampers meaningful comparison long-term trends between oceanic continental realms.
