Discovery and geologic significance of Late Paleozoic accretionary complexes in central Qiangtang, northern Tibet, China

Relevant studies have shown that the flysch clastic and schisteous basalt formation of Qiangtang metamorphic belt, central Tibet have commonly experienced a strong structural transposition. Also there are many early-late Paleozoic marble slices, rootless hook-shaped folds and isoclinal folds consist of marble and glaucophane schist. Eclogites formed at various ages exposed as blocks. These geologic bodies occur in slices and have experienced many phases of structure superposition and transposition. Original rocks in general are clastic rock, mudstone, siliceous rocks, carbonate rocks, pillow basalt and gabbro. Macroscopic regional foliation replacement indicates that this is typical orogenic zone accretionary complexes .
