Syn-collisional channel flow and exhumation of Paleoproterozoic high pressure rocks in the Trans-North China Orogen: The critical role of partial-melting and orogenic bending

► Oroclinal bending and partial melting controlled the flow and exhumation of the HPB. ► Partial-melting triggers strength drop and buffers a high thermal regime. ► Compressional forces were balanced by orogen-parallel lateral escape.
