Differential growth of the northern Tibetan margin: evidence for oblique stepwise rise of the Tibetan Plateau
Models of how high elevations formed across Tibet predict: (a) the continuous thickening of a "viscous sheet"; (b) time-dependent, oblique stepwise growth; and (c) synchronous deformation across Tibet that accompanied collision. Our new observations may shed light on this issue. Here, we use 40Ar/39Ar and (U-Th)/He thermochronology from massifs in the hanging walls of thrust structures along th...
متن کاملLate Cenozoic evolution of the eastern margin of the Tibetan Plateau: Inferences from Ar/Ar and (U-Th)/He thermochronology
[1] High topography in central Asia is perhaps the most fundamental expression of the Cenozoic Indo-Asian collision, yet anunderstandingof the timingandratesofdevelopmentof theTibetan Plateau remains elusive. Here we investigate the Cenozoic thermal historiesofrocksalongtheeasternmarginof theplateauadjacent to the Sichuan Basin in an effort to determine when the steep topographic escarpment tha...
متن کاملRapid slip-deficit rates at the eastern margin of the Tibetan Plateau prior to the 2008 Mw 7.9 Wenchuan earthquake
The Longmen Shan is the steepest topographic front at the India-Asia collision zone and the site of the Mw 7.9 Wenchuan earthquake. Here to explain the interseismic GPS velocities across the greater Longmen Shan region, we develop a boundary element model including earthquake cycle effects, topography, the westward dipping Beichuan Fault and a ∼20 km deep, shallowly dipping, detachment, inferre...
متن کاملDistribution of active rock uplift along the eastern margin of the Tibetan Plateau: Inferences from bedrock channel longitudinal profiles
[1] Current models of long-term river incision into bedrock suggest that the local rate of differential rock uplift should exert a primary control on the gradient of channel longitudinal profiles. However, discrimination of this effect from the influence of variations in substrate erodibility, sediment flux, precipitation, and transient changes in profile shape has proved difficult in practice....
متن کاملJoint inversion for crustal and Pn velocities and Moho depth in Eastern Margin of the Tibetan Plateau
a r t i c l e i n f o A classical problem in seismic tomography is the trade-off between a discontinuity location and the velocity of the medium. For that reason, crustal tomography and Pn tomography are typically done separately by isolating first-arriving Pg and Pn waves. Although this avoids the contamination of secondary arrivals because of the existence of the Moho, lots of good data are d...
