摘　　要：Most orogenic belts have experienced a complex accretionary process with multiple episodes of sea?oor subduction and trench retreat.This accretionary process is important in continenta development and growth[1,2].Three giant orogens extend in China,e.g.,the Central Asian Orogen in the north,the Central China Orogen in the middle and the Himalayan Orogen in the southwest.They are keys for the formation of the Eurasian continent(Fig.1a).The Central China OrogenMost orogenic belts have experienced a complex accretionary process with multiple episodes of seafloor subduction and trench retreat. This accretionary process is important in continental development and growth .
