///The Weipu granitic pluton and the Changpu migmatite are developed in the southern part of the Wuyi tectonic belt, South China.  Two rock samples taken from the NNE trending Weipu granitic pluton in southwestern Fujian were dated by zircons La ICPMS U Pb technique. The yield ages (447.1±4.7 Ma and 440.8 ±3.4 Ma) confirm that this granitic pluton belongs to the Caledonian in stead of Indosinian. The Changpu migmatite develops along the northern edge of the Luofu granitic pluton previously considered as Early Yanshanian age.
