大约自10Ma以来,南中国海板块沿马尼拉海沟的俯冲作用,已经在台湾和菲律宾海板块之间产生了一个弧-陆碰撞系。吕宋火山弧从东南向台湾方向的斜向碰撞作用使得该区碰撞前的沉积环境和构造特征发生了显著的改变,并使东南亚被动大陆边缘在中生代末以来进入相对稳定的旋回式沉积作用。碰撞作用的结果。不仅使得台湾中部地区快速隆起,而且台湾东部纵谷缝合带以西的碎屑楔状体组成的逆冲-褶皱带也产生弯曲。在过去的1.1Ma期间,中央山脉隆起的速率已从每年6mm增加到大约10mm。在西部山麓带到中央山脉西边,软弱的第三纪岩层中,褶皱作用和逆冲作用尤为强烈,它沿西北方向一直向前几乎影响到最前沿,那儿由固结的燕山造山带形成的台湾海峡地区为代表。这个薄皮构造的波前缘已经明显地自东向西逐渐移动。
Since about 10Ma, the subduction of the South China Sea plate along the Manila Trench has resulted in an arc-continent collision between Taiwan and the Philippine Sea plate. The oblique collision between the Luzon volcanic arc from southeast to Taiwan makes a significant change in the sedimentary environment and tectonic characteristics of the area before the collision, and makes the margin of the passive continental margin of Southeast Asia enter relatively stable cyclonic sedimentation since the end of Mesozoic. The result of the collision. Not only does the rapid uplift of the central Taiwan region occur, but also the thrusting-folding belt formed by the wedge-shaped crust of the west of Taiwan’s Rift Valley is bent. During the past 1.1 Ma, the rate of uplift of the Central Mountain Range has increased from 6 mm to about 10 mm per year. Folds and thrusts are especially strong in the weaker Tertiary formations west of the foothills of the western foothills to the west of the Central Sierra. Its trending along the northwest has almost reached the forefront, where Taiwan is formed by the consolidated Yanshan orogenic belt Strait area as the representative. The wave front of this thin skin has clearly moved gradually from east to west.
