七十年代末期以来,科学界将岩石圈作为固体地球科学研究的中心。本文拟对此作些说明,并对中国科学院这方面的工作谈点看法。 从两则新闻报道谈起 去年11月21日人民日报转载日本报纸的报道:“太平洋上的岛屿正以每年四至八厘米的速度向日本列岛方向移动。……这次实验首次测出太平洋板块的运动……。” 这一简短消息能够引起许多回忆。 1912年魏格纳提出大陆漂移说后,经过四十年代以后的洋底调查,于六十年代初又提出了海底扩张说。到了六十年代晚期出现了板块构造说,主张地球的岩石圈能分成若
Since the late 1970s, the scientific community has made lithosphere the center of solid earth science research. This article intends to make some explanations on this and gives some comments on the work of the Chinese Academy of Sciences in this area. Speaking from two press reports On November 21 last year, the People’s Daily reprinted the Japanese newspaper’s report: “The islands in the Pacific are moving toward the Japanese archipelago at an annual rate of 4-8 centimeters ... ... For the first time in this experiment, the Pacific plate Exercise ... ”This short message can arouse many memories. After Weissner proposed the mainland drift in 1912, after the ocean floor survey from the 1940s, he proposed the expansion of the seabed in the early 1960s. By the late 1960s plate tectonics said that the Earth’s lithosphere can be divided into Ruo
