英文摘要According to detailed work of petrology and structural geology, the Tongcheng HP-UHP (high-pressure and ultrahigh pressure) metamorphic belt in the southern segment of the Tan-Lu fault zone can be divided into three litho-tectonic units: upper low temperature HP unit, middle medium-temperature HP unit and lower UHP unit upper. Structural analysis indicates that the Tongcheng massif has experienced polyphase deformation (D1-D5) : D-1 represents the early stage of syn-collision exhumation process of the HP-UHP metamorphic rocks during the Middle-Late Triassic; D-2 represents the late stage of syn-collision exhumation process of the HP-UHP metamorphic rocks during the Late Triassic; D-3 corresponds to development of the Early Cretaceous central Dabieshan metamorphic core complex, which is also effect of the large-scale Late Mesozoic extensional tectonics in easterm China; D-4 might represent the strike-slip faulting of the Tan-Lu fault, superimposed on the HP-UHP metamorphic belt; D-5 is characterized by brittle faulting, and controled depvelopment of the Late Cretaceous-Paleogene Qianshan half-graben basin. These results suggest that the Tongcheng area experienced a complex tectonic history, which is difficult to explain by the model that the Tan-Lu fault dislocated the southern Dabieshan UHP metamorphic rocks to the northeast, and also does not support that there is robust evidence of huge strike-slip movement in the Tongcheng area.
