利用１４Ｃ、热释光（ＴＬ）样品年代及扩散方程计算结果，结合区域黄土剖面中古土壤年龄，对毛毛山地区晚第四纪各级地貌年龄进行了对比研究。根据毛毛山活动断裂水平位移和垂直位移分布明显的分组特征，求得毛毛山断裂带不同段落不同时段的平均滑动速率。大约自中更新世晚期以来，毛毛山断裂走滑段的平均水平滑动速率为２．３～３．９ｍｍ／ａ，垂直滑动速率为０．０７～０．１９ｍｍ／ａ；天祝盆地倾滑段垂直滑动速率为０．１１～０．８６ｍｍ／ａ。沿断裂带滑动速率具明显的非均匀性特点，表现为自东向西水平位移具累积滑动亏损特征，垂直位移则具补偿性
Based on the results of 14C, TL samples and diffusion equation, and combining with the ages of ancient soils in the loess section of the Loess Plateau, the geomorphologic age of the Late Quaternary in the Maomaoshan area was compared. According to the obvious grouping characteristics of horizontal and vertical displacement of active faults in Maomao Mountain, the average slip rate of different sections of Maomaoshan fault zone was calculated. Since about the middle Pleistocene, the average horizontal slip rate of the Maomaoshan fault strike-slip section is 2.3 ~ 3.9mm / a, and the vertical slip rate is 0.07 ~ 0.19mm / a. In the Tianzhu Basin, The vertical sliding rate is 0.11 ~ 0.86mm / a. The sliding velocity along the fault zone is characterized by obvious inhomogeneity, showing the feature of cumulative sliding loss from the east to the west and the vertical displacement with compensatory
