Keywords:Takanawa Peninsula, Granitoids in Ryoke belt, Whole-rock chemical compositions, Zircon U-Pb ages

In the Takanawa Pen. of northeast Shikoku Island, western Ryoke Belt, various types of granitoids are exposed. In this study, we present new whole-rock geochemical data together with new zircon U-Pb ages of the various types of Ryoke granitoids in Takanawa Pen. The distinctive geochemical trends together with discrete zircon U-Pb ages suggest that the granitoids in the study area crystallized from distinct magma batches at different times.
