摘要
以怀来八营槽为研究基础，分析研究了崩积物的沉积和岩相特征及其ＴＬ测年的适用性，并测定了样品的ＴＬ年龄．根据ＴＬ年龄及其岩相部位，在该探槽内可划分出两次断层活动事件：事件Ⅰ距今约２７ｋａ，事件Ⅱ距今约１５ｋａ．
The characteristics of colluvial dePOsitS in sedimentation and lithofacies and their applicability for TL dating were discussed, and their TL age measured.According to TL ages and lithofacies, tWo events for faulting were decided: event Ⅰ occured about 27 ha ago and eventⅡ about 15 ha ago.
