Abstract: On the basis of views of predecessers about the geotectonics in Zheijlang-Fujian on-land and its offshore,we proposed our opinion by terrane theory according to the information of geology,geophysics and radiometric age etc. This is a complex collision tectonics region of Precenoozic terranes,which can be divided into several elements from west to east,as follows: northwest Fujian terrane,Longquan collision zone,southeast Zheijiang、terrane,costal collision zone and Wen Don terrane. Zhoushan-Pinghu fault zone is a transverse fault (or an ancient transform fault),which separates this region from the north terrane which is fundamentally different in geology and geophysics. The Precenozoic evolution of the geotectonics in the region has undergone a very complex history of terrane drifting,collision juxtaposition and jump of subduction zone.

Key words: Zheijiang, Fujian, Terrane, collision-zone, collision tectonic region
