During the Triassic, a southward-directed subduction along its northern margin resulted in the Jin-Shajing suture, the limit between it and the Songpan-Ganzi terrane.
During the Late Jurassic and Early Cretaceous, the Lhasa terrane merged with its southern margin along the Bangong suture.
[1] This suture, the closure of part of the Tethys Ocean, transformed the Qiantang terrane into a large-scale anticline.
[4] The Qiantang terrane is now located at c. 5,000 m (16,000 ft) above sea level, but the timing of this uplift remains debated, with estimates ranging from the Pliocene-Pleistocene (3–5 Mya) to the Eocene (35 Mya) when the plateau was first denudated.
