"abstract": "The timing of crustal shortening and strike\u2010slip faulting along the East Kunlun Shan provides insight into the history of surface uplift and may constrain the time at which the Tibetan Plateau reached high elevations. We investigate a series of extensional basins and restraining bends along the Xidatan strand of the Kunlun strike\u2010slip fault, which provide an ideal setting to unravel the tectonic history of the northern plateau margin. We present new apatite (U\u2010Th)/He, apatite fission track, and zircon (U\u2010Th)/He ages and QTQt thermal modeling,\u00a040Ar/39Ar fault gouge dating, and structural mapping from the central East Kunlun Shan. Our data suggest that the East Kunlun Shan experienced slow to negligible exhumation until late Cretaceous time, followed by an increase in rate by 65\u201350\u00a0Ma. Along with a ~47\u00a0Ma fault gouge age, we posit that the Paleocene\u2013early Eocene was a time of crustal shortening along the northern plateau. Rapid exhumation along transpressional portions of the Xidatan fault initiated by 23\u201320\u00a0Ma, which we interpret as the local onset of strike\u2010slip faulting. An early Miocene transition from north\u2010south crustal shortening to left\u2010lateral shear along the East Kunlun Shan, the onset of normal and strike\u2010slip faulting in central and southern Tibet by 18\u00a0Ma, and lower crustal flow in eastern Tibet by 13\u00a0Ma suggest the establishment of orogen\u2010wide east\u2010west oriented extension and extrusion by the middle Miocene. The plateau\u2010wide shift in stress accommodation implies that high gravitational potential energy, and likely high elevation, was attained by the middle Miocene.",
