Abstract:

Based on the tectonic-geomorphic features,comparison of Quaternary system with isochron-ic geomorphic surface on both sides of the fault as well as the micro-and macro-structural indica-tions of the fault trace,the activity since late Pleistocene along the southern segment ofWuchuan-Sihui fault zone is discussed.It is suggested that this segment of the fault is relativelystable during this period.

Key words: Quantitative geomorphology, Fault activity’Thermoluminescent dating

摘要:

根据研究区的构造地貌特征,断裂两盘第四系和等时地貌面的对比以及其它宏观和微观的断裂构造迹象,讨论了四会-吴川断裂南段晚更新世以来的活动性,得出该时段、该断裂在该地区相对稳定的基本认识。
