| Abstract: | The features of epimetamorphic volcanic clastic rock bed association and its sporopollen assoliation of the Sinian in eclogites provide a basis of importance for determing the time for surfacial crust rocks in the Dabie Mt. and their correlation with the neighbouring area of strata. The determined turbidite,turbidty current deposit sequences and tectonic environments through diagnosis of the main deposit features in the area are gelogically significant to correctly recognizing the formation of environment and structural evolution of the orogen. |
