闽台地球动力学及其能态结构研究
|
摘要
台湾地处中国大陆东南边缘是菲律宾海板块凸向亚欧大陆俯冲-碰撞异常岛弧带。福建位于台湾岛弧西侧活动地块。闽台独特的构造格架、地球动力学状态和构造应力场与地震活动之间的内在关联性,使之成为研究海陆板块俯冲-碰撞效应及其对板内地震活动影响天然地区。本文主要依据近30多年以来对福建地块的地震地质背景、地壳变形观测、构造应力场、地震活动性以及地壳-上地幔结构探测、地热场等资料,结合台湾学者详细对台湾岛弧地球动力学与强震构造等研究成果,探索海陆板块俯冲-碰撞地球动力学特征及其对板内活动地块影响,进而揭示板间-板缘-板内强震活动关联性和动力学性状的异同性。试图为本区强震预测和防震减灾对策提供新思路。
Taiwan located in the southeastern brim of china mainland and it is a dive-collision singular island-arc zong from Filipine plate to Eurasia plate.Fujian located in the active land mass of the western side of Taiwan island-arc. The unique structure fram, geodynamical state as well as the intrinsic relationship between the structure stress field and seismicity that made it become a naturally region where the sea-land collision effect and its impact on seismicity in plate were researched.The paper mainly explored on sea-land plate dive-collision geodynamical feature and its impact on active landmass, according to the data that seismogeological background, crust distortion observation, structure stress field as well as crust-upper mantle structure exploring and geothermic field combining with the research results from Taiwan scholars to open out the similarities and differences between strong earthquakes and dynamical state ,so as to provide strong seismic prediction and earthquake prevention and disaster relief with a new idea.
