Cosmogenic dating, using in situ ²⁶Al and ¹⁰Be in quartz pebbles from alluvial terrace surfaces, constrains the late Holocene slip rate on the Xidatan segment of the Kunlun fault in northeastern Tibet. Two terrace risers offset by 24 ± 3 and 33 ± 4 m, having respective ages of 1788 ± 388 and 2914 ± 471 yr, imply a slip rate of 12.1 ± 2.6 mm/yr. The full range of ages obtained (≤22.8 k.y., most of them between 6.7 and 1.4 k.y.) confirm that terrace deposition and incision, hence landform evolution, are modulated by post-glacial climate change. Coupled with minimum offsets of 9–12 m, this slip rate implies that great earthquakes (M ∼8) with a recurrence time of 800–1000 yr, rupture the Kunlun fault near 94°E.
