Figure 3. (a) South-looking perspective view in the Xidatan–Dongdatan valley (see Fig. 2b for location). (b) Aerial photograph, and (c) corresponding sketch, where the Kunlun fault offsets left-laterally the terrace risers. T0–T3 indicate the terrace surfaces from lower to higher (i.e., younger to older). Numbers indicate the left-lateral strike-slip amounts of the terrace risers along the fault: the terrace risers T0/T1 and T1/T2 are displaced by 4.8 ± 0.5 m and 18.5 ± 2 m, respectively.
