中法两国地学科学家于1982年5月10日至12日在桂林举行了“第二次喜马拉雅山地质科学讨论会”。中方与会代表有李廷栋、叶连俊等28人,法国代表有奥贝尔(G.Aubert)、阿莱格尔(C.J.Al-legre)等13人。在会上肖序常等14位中国科学家、阿莱格尔等11位法国科学家宣读了论文,并进行了无拘束的讨论,从而为阐明喜马拉雅山地质构造特征、地壳与上地幔结构以及青藏高原的形成演化等提供了新的资料。 学术交流以大量实际材料讨论了日喀则蛇绿岩带西段低温高压蓝闪石片岩的存在,白岗累积层辉长岩、橄长岩等连续剖面(厚700米)的发现以及蛇绿岩常量和微量、稀土元素地球化学特征等资料,
Chinese and French geoscientists held the “Second Himalayas Geological Seminar” in Guilin from May 10 to May 12, 1982. There are 28 delegates from the Chinese side, including Li Tingdong and Ye Lianjun, and French delegates including 13 members including G. Abubert and C.J. Al-legre. At the conference, 14 Chinese scientists and Allegor and other 11 French scientists read the essay and held informal discussions so as to clarify the geological structure of the Himalayas, the structure of the crust and the upper mantle, and the formation of the Qinghai-Tibet Plateau Evolution provides new information.
