It is still controversial about when, where and how the East Paleotethys Ocean closed due to the lack of reliable paleomagnetic data from the blocks or terranes located in both sides of the suture, which prohibits our better understanding of a series of key scientific issues such as how major blocks of East Asia collided together, and the relationship between the major blocks of East Asia and the Pangea supercontinent before its breakup. This study reports paleomagnetic results from the Middle Triassic Hewanjie Formation limestones in the Baoshan Terrane, northernmost extension of the Sibumasu Block (Fig. 1). We aim to accurately reconstruct paleogeographic position of the Baoshan Terrane during this interval and to further discuss the timing and position of the Sibumasu-Indochina Collision.
