In eastern Qinling area, the Linting group can be divided into two lithological series by a large--scale ductile thrust shear zone of more than 100m wide and 200km long striking approximately E--W. North series is a sedimentary￣volcanic sequence,mainly composed of graywacke, volcanic lava, volcanic elastics and carbonitite which contains land-source sand, the metamorphic grade of which is low-middle. The closed, overturned and reclined folds and thrust faults are well developed. The sedimentary characteristics and provenance analysis indicates that it is the sedimentary rocks of the south active continental margin of North China plate from the last phase of early Paleozoic to the initial phase of late Paleozoic. South series is the ]and-source elastic sedimentary rocks with a great thickness, composed of low--grade metamorphic siltstone, polite, quartz sandstone and argillaceous carbonate with welldeveloped composite folds with steep dip axial planes, slaty cleavage and flow cleavage. The sedilnentrary characteristics and provenance analysis indicate that South Linting series formed in the north passive continental margin of Yangtze plate in the initial period of late Paleozoic. The two series have so many differences in rock formation, sedimemtary factes, metamorphism, deformation stage, fossil association and tectonic environment that they can be ascribed into two groups.
