The Sambagawa metamorphic belt in the north and the Mikabu greenstone belt in the south extend to the east and the west in the Ise district of eastern Kii Peninsula. Lenticular intercalations of pelitic, siliceous and basic schists occur along the Amabuchi River within the Mikabu greenstone belt. The pelitic schists frequently contain lawsonite. The mineral assemblages of the lawsonite-bearing pelitic schists is quartz+albite+chlorite+phengite+lawsonite±calcite. K-Ar phengite ages of the lawsonite-bearing pelitic schists occurring in the Mikabu greenstone belt and the pelitic schists of the Sambagawa schists are 93-99Ma and 84Ma, respectively. The Sambagawa schists in the northern Ise district and the Mikabu greenstones in the southern Ise district are correlated with Sambagawa schists (77-84Ma) and lawsonite-bearing schists of the Kebara Formation (89-103Ma) distributed in the Shimizu-Misato area, western Kii Peninsula.
