Simplified regional tectonic map of the eastern margin of the Tibetan Plateau. (a) Map showing the topography of the Tibetan Plateau and the location of Fig. 1b. (b) A simplified structural map and shaded topographic relief3,10,11. GPS measurements22 indicating current crustal deformation; the Min Shan and Longmen Shan regions are depicted by a primarily northeastward extrusion. Based on the thermochronologic data11,19,20, the Min Shan region has the highest uplift rate. The digital elevation data were downloaded from http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp. The topographic map was prepared using Generic Mapping Tools (GMT)36 (http://gmt.soest.hawaii.edu/). The map was drafted by X.X. using the CorelDRAW software package (http://www.coreldraw.com/en/product/graphic-design-software/).
