摘要
在前人对浙、闽及近海大地构造认识的基础上,根据地质、物探、同位素年代资料,按地体构造概念提出了我们的见解。本区是一个前新生代地体碰撞构造区,由西往东有下列地体及地体碰撞带:闽西北地体,龙泉碰撞带,浙东南地体,东南沿海碰撞带,温东地体。舟山-平湖断裂是分隔本区与北面不同地质区的平移断层(或古转换断层)。前新生代的大地构造演化就是这些地体漂移、碰撞拼贴和俯冲带跃移史。
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
