Most of the mineral springs found in the Abukuma Plateau are characterized by a low mineralization and a high pH, the waters being formed by a prolonged contact of granitic rocks with meteoric waters at low temperatures. The waters contain some fluoride, which is considered as derived from the rocks. With increasing pH, the F concentration also in- creases, with the highest value of 1.36 mg/l at the Aoba Mineral Spring, located near the Futaba Fault. The mineral spring waters issuing from the Ryoke Zone in Shikoku are similar to those from the Abukuma Plateau in the bulk chemical composition, but differ greatly in the F concentration. Those from the Ryoke Zone are much higher in the F concentration than those from the Abukuma Plateau, reflecting the difference in the F content between the granitic rocks from the Ryoke Zone and the Abukuma Plateau.
