It is widely accepted that the Central Asian Orogenic Belt （CAOB） is made up of widespread multiple ancient archipelagos. It has been recognized as a non-collisional orogen, contrasting with the archetypical Alpine- Himalayan-type collisional orogens. Although the CAOB is traditionally compared to subduction-accretion systems that have been well studied, all accretionary orogens ultimately passed into a collisional phase at the end of the orogenic Wilson cycle due to ocean closure and termination of subduction, which will lead to subsequent crustal shortening, thickening and reworking. Therefore, the archipelago-type CAOB may also preserve a terminal collision record, although this is not a classic continental collision at all.展开更多
