Tectonic analysis shows that the tectonic framework resulted from the compounding, transforming and superimposing of the two tectonic domains. The geodynamic mechanism of the transformation is mainly shown as the transverse and longitudinal heterogeneity of lithosphere, and the exchange between the crust and the mantle. 关 键 词：transformation of TECTONIC DOMAIN GEODYNAMIC mechanism SOUTHWESTERN Fujian Province southeastern China.
