Description

Early Cretaceous adakitic pluton consists of the adakitic granites in central part of zoned plutonic bodies (central facies) surrounding by adakitic to non-adakitic granites in marginal part (marginal facies). The exposure of the adakitic plutons is divided into two zones: from the eastern part of the north Kitakami belt to the eastern margin of the south Kitakami belt (E zone: Hashikami, Tanohata, Miyako, and Kinkasan plutons), and the inner part of the South Kitakami belt (W zone: Tono, Senmaya, and Hitokabe plutons). Zircon U-Pb age of the adakitic granites in W zone are younger than those in E zone, they are considered to be derived from higher pressure and vapor-present condition.
