Abstract: The Qinling-Dabie high-pressure (HP) and ultrahigh-pressure (UHP) metamorphic belt is one of the major constituents in the quasilatiludina1 global mobile belt of Mediterraean which has a long mobilization history. The HP-UHP rocks are developed in folded belts of various ages． In the Qinling-Dabie HP and UHP metamorphic belt the two HP and UHP metamorphic terranes, namely，the Qinling and North Hubei-Tongbai-Dabie，are subdivided by the delineation of the convergent suture of Dangfeng-Shangnan-Xinyang-Tongcheng fault. For the former, Qinling terrane, there are two HP belts in the south and north respectively. For the latter it is further subdivided into blueschist belt，HP／LT eclogite belt, UHP eclogite belt，HP／MT eclogite belt and eclogite-poor belt. All of them ace roughly symmetric in spatial distribution． The HP and UHP metamorhpic rocks are greatly diversified in various regions. They were even formed in different ages. Generally speaking, there are five stages of deformation, namely. HP-UHP stage (D1), HP-UHP metamorphic stage (D2), the formation of regional foliation stage(D3), ductile shear deformation stage(D4 ),uplift and exhumation stage(D5), comprising a complete deformational sequence． Based on the study of tectono-isotope chronology, five age groups have been obtained. The first group about 2000Ma is probably the protolith age of HP and UHP metamorphic rocks: the 2nd group of Jiningian (700~ 1000Ma) is the formation stage of HP metamorphic rocks；the 3rd group of Caledonian (400~ 540M a) represents the main period formation and metamorphic peak stage of HP-UHP metamorphic rocks the 4th group of Hercynian (271~ 326Ma)represents the retrogressive metamorphism of eclogites; the 5th group of Indosinion (205~ 243Ma)is another age of formation of HP metamorhpic rocks. Therefore, we can identify four tectonic evolution stages: Meso-Neoproterozoic stage, early Paleozoic stage, late Paleozeic to Middle Triassic, and the post-Triassic stage.
