摘要
台湾岛位于欧亚板块和菲律宾海板块的交界处,处在马尼拉海沟和琉球海沟两个方向相对的俯冲带的转换位置。由于从中新世以来吕宋岛弧与欧亚大陆斜向碰撞(弧陆碰撞)形成了今日台湾构造格局,特有的构造地质环境和正在进行中的块体增生使其成为地质学家的研究热点。针对吕宋岛弧海岸山脉段对弧陆碰撞的响应,本文综述了近年来海岸山脉年代学、地球化学、构造地质和利吉混杂岩等方面的研究成果,对海岸山脉的快速隆升和剥蚀特征进行了总结,并在此基础上指出了目前海岸山脉地质研究工作中存在的主要问题,提出今后的研究方向应集中在利吉混杂岩的形成机制、花东海盆洋壳性质和利用海岸山脉凝灰岩进行弧陆碰撞发展过程研究等几个方面。
Taiwan Island is situated in the active subduction--collision region between the Eurasian continent and the Philippine Sea plate. Tectonics in the Taiwan region is characterized by two opposite subduetion systems： Manila subduction system and Ryukyu subduetion system. The uplift of Taiwan results from the oblique collision of the Luzon arc and Eurasian margin. All of the geology characteristics attracted geologists all over the world. The Coastal Range is the onshore portion of the Luzon arc and is composed of deformed and accreted volcanic islands, intra-arc basins and forearc basins. Here we review geochronology, geochemistry, tectonic and geology research results of the Coastal Range and summarize the features of its uplift and erosion. We indicate the main research problems of the Coastal Range in the recent years. Meanwhile, some research directions about geology in the Coastal Range should be emphasized in the future, e.g. how the Lichi melange formed, the affiliation of the crust of the Huatung Basin, the process of the arc--continent collision recorded in tuff in the volcanoes and forearc basins.
