摘要
The Qinling is a complex orogen which has undergone multiphase collision among Yangtze Plate, Qinling microplate and North China Plate. As for the convergent age of Mian-Lüe ocean between Yangtze Plate and Qinling microplate, there are two opinions all along: Caledonian and Indosinian epoch. Well-preserved Early Carboniferous fossil radiolarias fauna firstly discovered from siliceous rock interlayers of ophiolitic melange near Sanchazi Village, Lueyang County indicate that the Mian-Lüe ocean basin lasted to late Paleozoic.
