Abstract The Triassic Pangaea was indented by a wedge shaped Tethyan Ocean spanning tropical and subtropical areas, with the Antarctic and Siberian Platform located in southern and northern high latitudes respectively. Configuration of the eastern Tethys is modified in this chapter on the basis of new data from palaeomagnetic, palaeogeographical, and geotectonic researches. This region displayed the interspersion of microcontinents and microocean basins, reminiscent of modern South-East Asia. North China (centred at Taiyuan, Shanxi) and Yangtze (centred at Emei, Sichuan) were at the palaeolatitudes of about 15°N and 2°N, respectively, during the Late Permian. However, North China had a rapid northward migration during the Permian and collided with Siberia-Mongolia in the Early Triassic. Later, Yangtze started to move northwards and merged with North China by the late Middle Triassic,
