The Lhasa massif is located in the south of the Qinghai Tibet Plateau, sandwiched between the the Yarlung Zangbo River suture zone and the Bangong Nu River suture zone, which are considered as geological relics of the eastward extension of the New Tethys Ocean. The Neotethys Ocean separated the Gondwana and Laurasia continents during the late Paleozoic to early Mesozoic era. Therefore, the determination of the paleogeographic location and movement history of the Lhasa block in the Permian period is of key significance to reveal the spatiotemporal evolution relationship between the Yarlung Zangbo River Ocean, Bangong Lake Nujiang River Ocean and the New Tethys Ocean. However, due to the scarcity of paleomagnetic data from the Late Paleozoic era, there is still controversy over the specific time and mechanism of the splitting of the Lhasa block from Gondwana, and a unified understanding of the early tectonic evolution model of the New Tethys Ocean has not yet been formed.
