我说放射性碳测定法太老旧

Based on technical processing of high-resolution SPOT images and aerophotos, detailed mapping of offset landforms in combination with field examination and displacement measurement, and dating of offset geomorphic surfaces by using carbon fourteen (14C), cosmogenic nuclides (10Be 26Al) and thermoluminescence methods, the Holocene sinistral slip rates on different segments of the Altyn Tagh Fault are obtained. The slip rates reach 17.5 mm/a on the central and western segments west of Aksay Town, 11 mm/a on the Subei—Shibaocheng segment, 4.8 mm/a on the Sulehe segment and only 2.2 mm/a on the Kuantanshan segment, a easternmost segment of the ATF. The sudden change points for loss of sinistral slip rates are located at the Subei, Shibaocheng and Sulehe triple junctions where NW-trending active thrust faults splay from the ATF and propagate southeastward.

在高分辨率SPOT卫星数字影像和大比例尺航片处理、断错地貌制图、野外核实与位移测量基础上，利用宇宙成因核素（10Be、26Al）、碳十四（14C）和热释光等多种测年手段，厘定了各断错地貌面的形成年龄，得到了阿尔金断裂带不同段落全新世左旋走滑速率：阿克赛以西的中、西段左旋走滑速率可达17.5 mm/a，肃北—石包城段为11 mm/a左右，疏勒河口段减少到4.8mm/a左右，东端宽滩山段仅约2.2 mm/a，左旋走滑速率突变点位于阿尔金断裂带中东段存在分支活动逆断层向南东扩展的肃北、石包城和疏勒河等三联点上。
