摘　　要：在南坑—虎门断裂跨断层钻探工作的初步结果上,对断裂的活动性予以简要阐述。通过对断层两侧钻孔岩芯的地层对比及年代学研究,建立跨断层钻孔剖面,并取得如下认识:南坑—虎门断裂未断错第四系覆盖层,晚更新世以来没有发现断层活动。Based on the preliminary drill results across the fault system for the project of ＂Active fault detection and seismic risk evaluation of Shilong-Houjie and Nankeng-Humen fault in Dongguan city＂,this paper discusses the activities of Nankeng-Humen fault developed in the Dongguan Basin. The composite drilling section at the two sides of the fault are established through stratigraphic correlation of the drills and the chronological data analysis. The major conclusion of this study is that there is no dislocation on the overlying Quaternary deposit and there is no evidence for the activity of this fault since Late Pleistocene.
