High-pressure/ultrahigh-pressure (HP/UHP) metamorphic zones mark the convergent lithospheric plate boundaries due to the paleo-oceanic crust subduction and continental collision,and record the geodynamic processes from subduction to exhumation of crustal materials (Simth,1988;Chopin,1984,2006;Carswell,1990;Maruyama et al.,1996;Ernst,2001,2006;Liou et al.,1998,2006,2009;Zheng,2003,2009;Powell et al.,2010,and their reference).The detailed studies of the type and space-time correlation,nature of the protolith and the ages of protolith,peak and retrograde metamorphism of the HP/UHP rocks can play a key role to understand the processes of the formation and evolution of orogenic belt.
