The Fujian coast Changle—Nanao metamorphism zone rocks are composed of gneiss, schist and hornblendite which had gone through metamorphism of amphilbolite facies, and followed the large-scale intrusive mass of gneissic granite. The zone was originally composed of Early Palaeozoic continental margin and island arc volcanic and sedimentary rocks. In 180-150 Ma, the zone underwent ductile shear deformation and amphibolite facies metamorphism; and in 130-80 Ma, rose rapidly and collided with the Southeastern China continental margin volcanic rocks along the NE trending ductile shear belt. The above geologic setting laid the present Fujian coast tectonic foundation whose formation and evolution are known to be interrelated with the subduction and collision of the Taiwan. Central Range.
