Abstract

Petrochemical studies of the plutonic rocks in the Abukuma Mountains are carried out. The leucocratic members (biotite granite – granodiorite) in the northern Abukuma Mountains have typical chemical characteristics of evolved granitic rocks. Granitic rocks in the southern Abukuma Mountains show chemical characteristics slightly different from those of granitic rocks in the northern areas.
