| 摘 要： | 对珠江三角洲地区布格重力资料系统处理、研究、解释，确认珠江三角洲地区地壳深部存在近EW向、NW向、NE向三组断裂。近EW向断裂是深部主要断裂，大部分断裂深及30km以上，其中有些断裂是以往很少为人们关注的。NW向断裂分布也比较广泛，但深度相对较浅，大都在10km左右，不超过20km。NE向断裂虽然地表出露最广，规模最大...

| Abstract: | According to our processing,analyzing and interpreting of the Bouguer gravity data,it is confirmed that in the crustal deep level of the Pearl River Delta region,there are three fault systems with the directions of the EW,the NW and the NE respectively.The EW fault is the main fault system in depth and its depth of most part is over 30 km.According to this interpretation,the depth of the EW direction fault is about 10 km,although it is formerly considered as an abyssal fault.The NW faults are distributed in... |
