| 摘 要： | 通过对福建东南沿海海拔50m以下几个地貌面的时代确定,研究了长乐-诏安NE向断裂带和与之相交切的NW向断裂带第四纪以来的活动性。结果表明:区内50m以下几个地貌面分为侵蚀-剥蚀阶地和堆积阶地,属晚更新世以来几个时期所形成;断裂在切割某个地貌面时,其地貌面的形成年代可确定为该断裂的活动年代;长乐-诏安NE向断裂带中的平潭青峰-东山澳角断裂的有些地段为晚更新世晚期(Q3p)活动断裂,垂直滑动速率为1.1～2.2mm/a;长乐-东山前梧断裂主要活动时代在中更新世(Q2p);九龙江下游NW向断裂带中的江东桥(北溪)-海沧断裂,其NW段江东桥(北溪)断裂为早第四纪(Q1p-2)断裂,SE段海沧-钱屿断裂为晚更新世(Qp3)活动断裂

| Abstract: | In this paper,the fault tectonic activity of Fujian southeastern coastal region since the Quaternary is analyzed by studying the formation and development of several geomorphic surfaces below 50m.The results show:(1)the geomorphic surfaces below 50m in southeastern coastal region of Fujian can be classified into erosion-abrasion terrace and accumulational terrace.The former(mostly,red soil platforms)can be divided into 3stages:the elevations above sea level are 10～15m for T1,20～25m for T2 and 40～50m for T3 |
