摘要
通过对东特提斯地区有关地块编制地质时代——古纬度图,我们得出如下结论:①东特提斯开始形成于奥陶纪末——志留纪初;②东特提斯洋主体由特提斯——Ⅰ和特提斯——Ⅱ二支海槽组成,其间被中间地块或岛群断续分开;③藏北、藏南、帝汶等地块来自冈瓦纳,而中伊朗、塔里木、斯兰等地块(或岛)来自欧亚。这些结论也被各种地质资料所证实。图2,表12,参13。
Based on the Geological time-palaeo-latitude map for East Tethys, We Conclude that ① The time of formation of East Tethys was the end of Ordovician to the beginning of Silurian period. ② The main Tethys is composed of Tethys-Ⅰ and Tethys-Ⅱ, between them are some central blocks or islands. ③ the North Tibet. South Tibet and timor blocks were rifted from Gondwana; but the Central Iran, Tarim and Seram blocks were rifted from Eurasia. These Conclusions are Confirmod by Various geological data.2figs., 12tabs., 13refs.
