摘要:

中国台湾的大地构造格局和晚中生代以来的演化过程一直是地质研究的难点和热点,特别是对其构造单元的类型、性质和演化过程存在较多争论.本文系统综述了50多年来已有中国台湾大地构造格局和重建晚中生代以来构造演化史的主要认识,特别是近10年来新的研究成果,侧重探讨了板块运动和弧陆碰撞对中国台湾大地构造形成过程中起到的作用.研究认为中国台湾总体经历了4个关键期:(1)晚中生代太平洋活动大陆边缘时期(约80 Ma),在华南陆缘形成造山带和俯冲沟弧盆系统;(2)古近纪到早中新世被动大陆边缘时期(约80~16.5 Ma),形成新生代台西盆地和台西南盆地雏形;(3)中-晚新世板块汇聚初期(16.5~6 Ma),形成的马尼拉海沟北段俯冲增生楔为中央山脉、恒春半岛前身,向南连接恒春海脊,部分南海洋脊因碰撞挤压形成中国台湾东部蛇绿岩套;(4)晚中新世末以来活跃造山期(6 Ma至今),菲律宾海板块朝欧亚大陆向西碰撞和向北俯冲,分别形成西部麓山带、雪山山脉、高屏斜坡和大屯火山区—琉球火山弧、宜兰平原—冲绳海槽;北吕宋岛弧向欧亚大陆碰撞和逆冲,形成花东纵谷和利吉混杂岩体、海岸山脉.中国台湾地区在同裂谷(syn-rift)时期的晚白垩系到古近系、后裂谷(post-rift)时期的中新统、造山定型期的下中新统和第四系地层发育了三套主要含油气系统.从大地构造格局和演化来认识中国台湾独特的发生、发展规律,从而理解其独有油气和天然气水合物成藏规律,这对该区油气和天然气水合物的寻找和评价具有指导意义.

Abstract:

The tectonic framework and evolution process of Taiwan since late Mesozoic have been the difficulties and hotspots of geological research. Especially, the types, properties and evolution process of tectonic units are always uncertain and controversial. This paper systematically reviews the main understanding of structure evolution and evolution history reconstructing of Taiwan in the last 50 years, especially the recent advances in the latest decade focusing on the role of plate movements and arc-continent collision to the formation of Taiwan tectonics. The study suggests that Taiwan has experienced four critical periods: (1) in the Pacific active continental margin period (about 80 Ma), formed orogenic belts and trench-arc-basin subduction system along the Southern China continental margin, (2)in the passive continental margin period (about 80~16.5 Ma), formed the original Cenozoic West Taiwan Basin and Southwest Taiwan Basin, (3) in the initial collision period (about 16.5~6 Ma), subduction accretionary prism on northern segment of Manila trench is the predecessor of the Central Range and the Hengchun Peninsula, south or it connecting the Hengchun ridge, and some of the South China Sea ridge became ophiolite suite in eastern Taiwan caused by collision and compression, and (4) in the active orogenic period (about 6 Ma to present), the Philippines Sea plate westward colliding and northward subducting toward Eurasia plate, and formed the Western Foothill, the Xue mountains, the Gaoping Slop, the Tatun volcano area-Ryukyu volcanic arc, and the Yilan plain-Okinawa trough. The northern Luzon volcano arc collided and thrust against the Eurasian continent, and formed the Longitudinal Valley of Eastern Taiwan, the Lichi Melange and the coastal mountain ranges. Three major petroleum systems have been developed in Taiwan. They are the late Cretaceous to the Paleogene formation in the syn-rift period, the Miocene formation in the post-rift period, and the lower Miocene and quaternary formation in the orogenic period. Tectonic framework and evolution is important for understanding the formation of Taiwan and its reservoir-forming rules. It is of guiding significance for evaluating oil, gas and natural gas hydrates in this area.
