In the Qinling orogenic belt, oceanic crust originated in the Early Palaeozoic, while the product of continental collision appeared as late as after the Triassic. The Late Palaeozoic records there are of major impor‐tance for understanding the tectonic regime at that time. The Carboniferous and even Permian sequences and the distribution of sedimentary facies in northern Huaiyang indicate that the rocks were formed in a large basin opening towards the south. Regional stratigraphic correlation shows that the interior of the Qinling orogenic belt was a sea trough lying between the Yangtze and North China plates in the middle part of the Late Palaeozoic. With subsequent northward migration of the South China Sea, the two seas were connected with each other. Both the mélanges and the Dabie block in the eastern sector of the Qinling belt were formed in the Mesozoic 1 .
