Evidence and dynamics for the change of strike-slip direction of the Changle–Nanao ductile shear zone, southeastern China

摘要: Abstract The Changle–Nanao ductile shear zone was developed from a suture zone. evidence the fabrics and mylonitic microstructures indicates that strike-slip sinistral during pre-collision. It became dominantly dextral in syn-collision stage late Early Cretaceous. movement continued post-collision with extension as dominant process. of strictly controlled by dynamics collision between Fujian (Min)–Taiwan (Tai) microcontinent (Min)–Zhejiang (Zhe) Mesozoic volcanic arc time interval 100–120 Ma. Min–Tai which might have been located originally to south its present position. northward migration had contributed few hundred kilometers drift rather than displacement. real displacement is small due change direction dextral.
