“…The ages of the terraces at Pishan have not been directly determined, but as the formation of terraces is likely to be climatically controlled, we can estimate a likely age range from terrace abandonment dates from elsewhere, provided that the two places have a similar climatic history over the relevant time period. Dating from aggradational terraces around the Tarim Basin and the Qilian Shan, 250–800 km distance from Pishan, has found ages from a few thousand years to >140 ka (e.g., Avouac & Peltzer, ; Li et al, , ; Mériaux et al, ; Saint‐Carlier et al, ) and slightly farther afield Stockmeyer et al () recently dated a suite of terraces on the northern front of the Tien Shan as 5–212 ka. Given that present‐day GPS velocities could allow no more than 3 mm/yr in the strike‐perpendicular direction (Ge et al, ) and that the oldest of the terraces (Tw10 and Tw9) are deformed vertically by at least 120 m (Figure ), it is likely that the oldest Pishan terraces are toward the older end of these age ranges.…”
