///Based on the Sino-France cooperated regional tectonics investigation of the middle part of the Caledonian orogenic belt in South China, SEM studies on nano-sized particles and dynamic thin-shell or films in different kind of ductile shear zones from Neoproterozoic to Mesozoic (ductile cleavage zone, thrust fault zone, extrusion schistose zone, tensile structural zone) in Wugongshan were carried out. Then, the authors discussed the system dynamics on the time delay of the Caledonian orogenic belt in
