【摘要】 台湾位于欧亚板块与菲律宾海板块的交界带,中中新世开始的吕宋岛弧与欧亚大陆边缘碰撞造山运动形成了现今台湾及其附近海域的基本构造格局和特有的区域地质特征。通过对台湾岛地质考察和研究区各种调查资料的分析,总结台湾及其附近海域区域地质特征,具有出露地层新、构造活动年轻且强烈、受马尼拉和琉球两个俯冲带共同影响等特点;研究区的新构造运动主要受到弧陆碰撞的影响,表现出各种断裂作用极其发育、逆冲-褶皱带多见、火山和地震活动频发、地热温度比较高等特征,研究区中西部麓山带和台东纵谷-海岸山脉以及台湾南部和东北部海域是新构造运动的活跃区。更多还原

【Abstract】 Taiwan is located at the junction of the Eurasian Plate and the Philippine Sea Plate.The tectonic framework and regional geological features of the inland and its offshore owe their origin to the collision of the Luzon Arc and the Eurasian Continent(arc-continent collision)in Middle Miocene.We summarized in this paper the regional geological features of the study area based on field geological observation and survey data.The geology of Taiwan is characterized by young strata,strong and young active tectonics and the influence of both Manila subduction and Ryukyu subduction.The neotectonic movement in Taiwan is also effected by arc-continent collision.There are numerous faults,thrust-fold belts,frequent volcanic eruptions and earthquakes and higher geothermal anomalies in the study area.Neotectonic movement is particularly active in the Western Foothills,the Longitudinal Valley-the Coastal Rang and the southern and northeastern seas.更多还原
