菲律宾海构造地貌特征

THE TECTONIC GEOMORPHOLOGY OF THE PHILIPPINE SEA

  • 摘要: 菲律宾海地处西太平洋边缘,位于两大俯冲带之间,四周被深海沟所环绕,陆源物质较少汇入,海底保存了较为原始的构造地貌特征。通过收集的精细水深测量数据,结合已有研究成果,以板块构造为基础对该区域划分四级构造单元,并对主要构造地貌进行系统研究。研究结果表明,菲律宾海地貌的形成、分布受构造活动控制,西菲律宾海盆因以中央裂谷带为中心的海底扩张形成了一系列NW-SE向的大型构造地貌;其东侧因太平洋板块的俯冲形成了近南北走向的"沟-弧-盆"体系。西菲律宾海盆中央裂谷带线状海岭、海山,海盆内不断转向的海岭,帕里西维拉海盆雁形裂谷等特殊地貌形态的存在,都与其形成过程中的特殊性有关,能与其复杂发育史相印证。

     

    Abstract: The Philippine Sea is located at the West Pacific, between two large subduction zones. The sea is surrounded by a deep trench, in which there is little terrigenous import, so the original landscape features are well preserved. According to the exact water depth data, combined with the existing research results, and under the regime of the plate tectonics, this area is divided into four tectonic units, and the main tectonic geomorphology system is studied. The results show that the shape and distribution of topography in the Philippine Sea are controlled by tectonic activity. The west Philippine Sea Basin is characterised by a series of large tectonic geomorphology of NW-SE directions, due to the seafloor spreading of the central rift zone; the east Phiilippine Sea Baisn characterized by a N-S trench-arc-basin system because of the subduction of the Pacific plate. There are some linear ridges and seamounts around the central rift zone, continuous steering ridges in the basin, and echelon rift valleys in the Parece Vela basin. Such a pattern of geomorphology is all related to its special process of formation, corresponding to the complex evolutionary history.
