The crust in the Dabie orogenic belt has a tectonic form of imbricated plates. The regional crust can be divided into three structural layers, and in the middle crust, there exist a low-velocity layer and a low-electrical resistivity layer. The crust of the orogenic belt has a granodioritic composition, and the deep crustal composition is mediosilicic. The crust is characterized by high 2 REE, a high degree of LREE and HREE fractionation, depletion in ferromagnesian elements and enrichment in lithophile elements in comparison with the values of Weaver and Tarney (1984), Taylor and Mclennan (1985), Shaw et al. (1986), and Gao Shan, Zhang Benren et al. (1990). An obvious lateral compositional difference exists inside the orogenic belt, whereas the vertical chemical differentiation from the lower to the upper crust is poorer than that of other well-studied continental crusts.
