The Fufang granitoid pluton,outcroped in the middle part of oft-com:office:smarttags" />Wuyi Mountain area, is a typical Early Paleozoic pluton in the eastern segment of South China. Based on large amount of geological data during regional geological survey, the authors carried out a systematic study on petrography, geochemistry and LA-ICM-MS zircon U-Pb dating for the Fufang pluton. The research results show that the Fufang pluton is of S-type granite, derived from the continental crust by lower degree of partial melting and its source rocks were mainly composed of pelitic sandstone rocks. oft-com:office:office" />
