文中参照各家关于台湾海峡及邻区的地质构造和演化的观点,依据作者的野外考察和室内研究成果,列举了一些鲜为人知的事实和困难,以澄清海峡两岸的构造联系和差异,肯定了浙闽结晶基底属于古亚洲大陆并发育为加里东地槽,而台湾结晶基底与板块俯冲密切相关。上覆岩系反映了地壳运动所导致的海侵、海退旋回,中生代的火山活动和板块碰撞。该区的北东向断裂愈临近太平洋板块活动强度愈大,时代较新的北西向断裂在海峡两岸均有走滑压性特征。文中详述了在基底构造、上覆岩系、断裂系统方面需要深化的认识。
In this paper, according to the opinions of various authors on the geological structure and evolution of the Taiwan Strait and its adjacent areas, some unknown facts and difficulties are listed based on the author’s field investigation and indoor research to clarify the tectonic relations and differences between the two sides of the Taiwan Strait. The Zhejiang-Fujian crystalline basement belonged to the ancient Asian continent and developed into the Gallinger trough, while the crystalline basement of Taiwan is closely related to plate subduction. The overlying strata reflect the transgression caused by the crustal movement, the exhumation, the Mesozoic volcanic activity and the plate collision. The NE-trending faults in the area are more active in the Pacific plate, and the NW-trending faults in the age have strike-slip characteristics on both sides of the Taiwan Strait. The article details the need to deepen the understanding of the basement structure, overlying rock series and fault system.
