国外海洋岩石圈深部结构的地震学研究进展
|
摘要
近十年来,深地震反射波勘探在海洋岩石圈的形成与演化、地壳结构研究中的应用越来越广泛.本文介绍了美、英、法及北欧一些国家在北海、波罗的海、挪威海、大西洋、太平洋,地中海等海域分别进行的垂直入射、宽角反射/折射地震试验,及其在大陆边缘构造、海洋地壳的演化、海底断裂形态、性质等方面的研究成果
In the recent decade,the deep seismic reflection profiling has been applied widely to studies on formation and evolution of oceanic lithosphere,crust structures and so on. America、Britain、France and other countries in Northern Europe have conducted the deep seismic reflection、wide-angle reflection/refraction experiments in Pacific、Atlantic North Sea、Mediterranean、Baltic Sea et al,respectively. In this paper,the researched results from the experiments on continental margin structures、evolution of oceanic crust、shapes and characters of the faults at oceanic bottom are presented.
