中国地学热点研究区几个地学问题的探讨

中国(大陆及其周边地区)一直是全球地学研究的前沿阵地,是全球陆-陆碰撞造山、海洋岩石圈俯冲和古大陆岩石圈演化动力学研究的理想实验室。几十年来,地学家们通过地质调查与地球物理、地球化学等相结合的研究,取得了许多新进展与新发现。笔者对青藏高原、西太平洋俯冲带、华北克拉通和南北地震带等地区多年来一直存在争议的几个重要地学问题进行了简要的总结,并从地震学的角度出发,对问题的解决提出了粗浅的见解与看法。

Study on Some "Hot Spot" Areas of Geo-Sciences in China

Chinese mainland and its neighboring areas are regarded as the ideal laboratory for the geodynamical study of continent-continent collisionnal orogens,ocean lithosphere subduction and the evolution of the ancient-continental lithosphere.Since last several decades,considerable efforts have been made to study the geodynamic problems through both geological and geophysical investigations in China.Great progress has been made in some "hot spot" areas of the geoscientific research,such as the Tibetan plateau,the western Pacific subduction zone,the North China Craton and the South-north seismic belt.In this paper,some important problems remain controversial are summarized and presented.From seismological point of view,some points of the solution to these debate are proposed.
