%X Abundant microfossils have been found in the Nanwan Formation of the former Xinyang Group, which is consistant with the Devonian Liuling Group in the Qinling Mountains in age and sedimentary-structural characteristics. Also, abundant Early Paleozoic microfossils and a few corals have been discovered in the Erlangping Group, whose sedimentary sequence represents the process from sea-floor spreading to subduction of the ocean basin. The tectonic zones of the Qinling Mountains and the Tongbai-Dabie Mountains may link up one another, and the main suture zone is situated along Danfeng-Xinyang-Shucheng. It is the Guishan Formation of! the former Xinyang Group that is the strongly deformed pre-Devonian tectono-stratigraphic unit distributed in the main suture zone. The result of the systematic, isotopic dating clearly shows that the Qinling Mountains are a Caledonian, Variscan, Indosinian, and Yanshanian polycyclic composite orogen. The Sinian to Triassic sequence on the southern edge of the Sino-Korean platform has recorded the evolution of the Qinling orogen in different aspects of its process. The Cretaceous-Tertiary Hehuai basin was generated owing to the combined effect of the Tethys and Pacific Ocean dynamic systems.
