东特提斯显生宙的演化包括3个连续洋盆的张开和闭合,即古特提斯、中特提斯和新特提斯。3个洋盆的张开是3个长条形陆块从冈瓦纳古陆边缘断裂、分离并向北漂移的结果(图1,略)。古特提斯洋盆的形成始于泥盆纪,当时第一次大陆裂解,包括华南、华北、塔里木和印支板块,从冈瓦纳古陆分离出来(图2,略)。中特提斯的形成始于早二叠世晚期至中三叠世,此时第二次陆块裂解,包括西布玛树板块、羌塘板块和基梅里大陆的其它板块,从冈瓦纳古陆分离出来(图3,略)。新特提斯开始于第三次大陆裂块分离之后的晚三叠世至晚侏罗世,第三个大陆裂块包括拉萨板块、缅甸西部以及现在位于苏 The evolution of the Eastern Tethyan Phanerozoic consists of the opening and closing of three consecutive oceanic basins, namely, the ancient Tethyan, the Middle Tethys and the Neo-Tethyan. The opening of the three ocean basins was the result of three long bar-shaped blocks fractured from the margins of the Gondwanaland and separated and drifted northward (Figure 1). The formation of the ancient Tethyan ocean basin began in the Devonian, when the first continental cleavage, including the South China, North China, Tarim and Indochina plates, separated from the Gondwanaland (Figure 2). The Middle Tethys began to form from the late Early Permian to the middle Triassic. At this time, the second block rupture, including blocks from the Sibuma Tree, Qiangtang and Kimberley, Ancient land separated (Figure 3, omitted). The Neo-Tethyan began in the late Triassic to late Jurassic after the third continental fission, and the third continental block consisted of the Lhasa Plateau, western Burma, and now the Soviet Union
