Constraining the Karakorum fault (KF) slip-rate is essential to understand the present-day kinematic role of large strike-slip faults in the deformation of Tibet.Its currently published range of geodetic and geologic slip-rates is ~0 – 11 mm/yr.New offset geomorphic features (38±5 to 220±20 m) add new quantitative information on its late Quaternary slip-rate.Their ages were determined using 10Be surface-exposure dating of 92 samples collected on one moraine and at 3 alluvial sites along the Bangong – Chaxikang and Gar basin segments,southeast of Bangong Lake.The slip-rate is 2.9(+1.0/-0.6) mm/yr at GUN,>5.3(+4.3/-1.7) mm/yr at CK and >5.3(+3.1/-2.3) mm/yr at GF,in agreement with that determined to the southeast (>5.5±0.5 mm/yr at Manikala on one strand for the 0 –40 ka period,7.1(+3.2/-1.7) mm/yr at Menshi and 7.9(+3.2/-2.5) mm/yr near the Kailas,across two strands)and to the northeast (4±1 mm/yr at Tangste).Taken together with the rate along the northernmost tip of the KF in the Pamir (>5 mm/yr),we suggest that the minimum late Quaternary slip-rate along the entire length of the KF may be relatively constant along-strike at >5 mm/yr on one branch or >7 mm/yr across two branches.In addition to being spatially constant,this rate appears to be,within error,in agreement with most studies at various timescales and suggests that at first approximation,no major discrepancy exists between geodetic and geologic rates.
