引言 我国著名地质学家尹赞勋、李春昱先生1972年先后将板块构造理论引入我国,至今仅十个年头。开始曾有人担心:奠基于海洋地质的海底扩张和板块构造理论能否在“大陆地质”的研究中得到验证,而表现在现代地质中的板块运动记录又是否能在漫长的地球历史中反映。随着板块构造研究的不断深入,特别是赫斯、迪茨的研究,提出蛇绿岩实际上代表大洋岩石圈的碎块以后,近年来已有越来越多的人根据优地槽中蛇绿岩的分布
Introduction Well-known geologists Yin Zanxun, Li Chunyu 1972 plate tectonics theory has been introduced into our country, so far only ten years. Initially, some people have been worried about whether the seabed expansion and plate tectonics based on marine geology can be verified in the study of “continental geology,” and whether plate motion recorded in modern geology can be reflected in the long history of the earth. With the deepening of researches on plate tectonics, especially the study of Hess and Dietz, it is suggested that after ophiolite actually represents the crust of the oceanic lithosphere, more and more people in recent years have been based on the snake The distribution of greenstone
