摘要
中国东南沿海存在两条重要的地体边界,一条分布于松阳—政和—清流,是古华夏地体与东南沿海地体的边界。它代表中元古代扩张裂解而于早古生代完成碰撞闭合的古缝合带。另一条边界出露于台湾海峡西岸的平潭—东山地体内。它于早白垩世方移置于大陆边缘,至今仍在活动,是地震活动带之一。两条地体缝合带所代表的两次碰撞是东南沿海两次最重要的地质事件。
There are two significant terrane boundaries in southeastern coast of China. One of them extends along Songyang- Zhenghe- Qingliu and is the boundary between Proto- Cathaysia Terrane and Southeastern Coast Terrane. It represents the palaeosuture resulted from the extension during Middle Proterozoic era and the collision during Early Palaeozoic era. The other is situated in the western side of the Taiwan Strait inside the Pingtan--Dongshan Terrane, which was displaced to the continental mar gin in Early Cretaceous period. The seismic activities along this belt indicate the current continuous movement of the terrane. These two terrane sutures represent two collisions which are the most impor rant geological events in southeastern coast of China.
