In Sanuki plain of NE Shikoku island, many small volcanic bodies belonging to Setouchi Volcanic Rocks are distributed. We report new 24 whole rock compositions of felsic members of the Setouchi Volcanic Rocks analyzed using XRF.Some of the samples are "adakitic" with low Y content and high Sr/Y ratio, as previously reported for Setouchi Volcanic Rocks from Kii peninsula and Shodoshima Island. All of the adakitic rocks are rhyolitic composition with SiO2>73% , and may be derived from distinct magma patch from coexisiting low Sr/Y ratio andesite to dacite.
