| 摘 要： | 根据对冷龙岭断裂重点地段的野外调查，研究了该断裂的几何特征及浮雕劝速率。结果表明：该断裂为一条全新世活动断层，由一组近于平行的次级断裂所组成。按总体特征可将该断裂分为３段，中更新世以来各时代的断裂平均滑动速率分别为：中更新世：２．１４～４．６４ｍｍ／ａ，晚更新世：２．８６～４．０７ｍｍ／ａ，全新世：３．３５～４．６２ｍｍ／ａ，全新世以来该断裂平均垂直滑动速率为０．３８ｍｍ／ａ。

| Abstract: | Based on data of field investigation in major area of Lenglongling fault zone,geometric characteristics and slip rate of the fault zone are studied.The results show that the fault zone is an active one in Holocene and consists of a group of secondary faults.According to its total characteristic,the fault zone can be divided into 3 segments.The average left lateral horizontal slip rates of the fault zone since middle Pleistocene are calculated.The horizontal slip rate in middle Pleistocene is 2.14~4.64 mm/a,the rate in Epipleistocene is 2.86~4.07 mm/a,the rate in Holocene is 3.35~4.62 mm/a.The vertical slip rate is 0.38 mm/a since Holocene. |
