台湾岛位于沿菲律宾海西缘展布的琉球岛弧和吕宋岛弧的结合处．台湾岛以南，南海岩石圈向东俯冲到吕宋岛弧之下．台湾岛以东，菲律宾海板块向北俯冲到琉球岛弧之下．晚新生代，由于吕宋岛弧与亚洲大陆的碰撞，形成了台湾山带，台湾山带的构造走向为NNE－SSW，其弧凸向亚洲大陆 Taiwan Island is located at the junction of the Ryukyu Island arc and the Luzon arc along the western edge of the Philippine Sea. To the south of Taiwan Island, the South China Sea lithosphere dive to the east under the arc of Luzon Island. To the east of Taiwan Island, the Philippine Sea Plate subducts northward to the Ryukyu Island arc. Late Neo-Cenozoic, due to the collision of the Luzon arc with the Asian continent, a mountainous belt was formed in Taiwan. The tectonic orientation of Taiwan’s mountain belt was NNE-SSW, with its arc protruding toward the Asian continent
