摘要：

[1] Seismic tomographic image reveals a crocodile-like P-waves velocity structure beneath the Sulu orogenic belt, which marks the subduction/collision zone between the Sino-Korean block (SK) and Yangtze block (YZ) in eastern China. It may imply that the upper crust of the YZ was detached from its lower crust and thrust over the SK for a maximum of similar to400 km in the Sulu region, whereas the remnant of the subducted Yangtze lithosphere was lay beneath the SK. This crustal detached structure (flake tectonics) might have occurred after the Triassic subduction/collision.
