The trace element composition and zircon U–Pb age of granites from the Iwafune pluton were investigated to reveal the relation between the Takatori deposit and the granite. The granites are ilmenite series and contain high amount of Ga, Rb and Sn. The zircon U–Pb age of the granite lies within the range between the age of forming the Takatori deposit and the minimum age of aplite from that. The results are indicated that the granite of the Iwafune pluton might be associated with the granite that formed the Takatori deposit.
