Each of the two models makes a different prediction for reactivation along the Bangong suture. The soft Tibet model suggests that a series of small multiple faults along the suture zone would occur, due to the ductile nature of the lithosphere. Based on the micro-plate tectonics model, large strike-slip faults with significant displacement should be present. Crustal extrusion (in the form of sinistral strike-slip faults) should also be present and would be caused by oblique subduction at the edges of the suture zone. Understanding the evolution and structure of these faults as well as other boundary faults (faults that surround the Tibetan plateau) is important to constraining the formation and deformation of the Tibetan Plateau. Research to identify features in the field that would satisfy either of these hypotheses is ongoing.
