Correlation between Tongbai and western Dabie orogenic belts has been discussed based on available data that suggest the Tongbai and western Dabie orogenic belts can be devided into 7 and 10 structural units,respectively.The north five units of the two orogenic belts can be correlated and resumed as the Paleozoic active continental margin of the North China plate,indicating both the Tongbai and western Dabie suffered a Paleozoic subduction of Yangtze plate.To the south,The Xiongdian ecologite in the Xiongdian-Huwan ductile shear zone implies the occurrence of the Paleozoic HP metamorphism.However it is difficult to recognize the exact distributing range and tectonic unit of the HP metamorphism.Whereas the other Mesozoic HP-UHP rocks occurred in belt-shaped and dome-shaped occupy the major part of the Mesozoic orogenic belt in Tongbai and western Dabie areas,forming the line and dome structural units that can be correlated each other.Because the frameworks of both the Tongbai and western Dabie are composed of the Paleozoic arc-continent collision orogenic belt in the north part and the Mesozoic orogenic belt formed by uplift of the HP-UHP rocks in the south part,both of them are characterized by the multiple Paleozoic and Mesozoic orogenic belt.In view of structural units and tectonic evolution,both of them are be correlated each other.
