The Changle-Nan'ao ductile shear zone might develop from the collision suture zone. The strike-slip movement was strictly controlled by dynamics of collision between the Fujian-Taiwan microcontinent and the Fujian-Zhejiang Mesozoic volcanic arc. Analyses of the ductile fabrics and mylonitic microstructure suggest that strike - slip was sinistral in the early stage of collision. It became dominantly dextral in the late Early Cretaceous main-collision stage (120 - 100 Ma B. P. ). The dextral strike-slip movement continue in the late collision stage with extension as the dominant process and even up to now. The Fujian-Taiwan microcontinent (or called the Pingtan-Dongshan belt) where the ductile shear zone developed might be originally located to the south of the present position, which was altributed to a few hundred kilometers of drift rather than shear displacement.
