The zircon dating was performed from the Sangun metamorphic rocks in the northern Kyushu. Crystalline schists in Kurume-Yamaga area, southern Fukuoka belong to the Suo belt and showed various detrital zircon age spectrum. Those in Sasaguri area, central Fukuoka showed different age spectrum of detrital zircons from previous reports (Tsutsumi et al., 2003, 2011). The results reflected the variation of their detrital provenances.
