| Research Abstract |
Magmas erupting on the earth's surface have experienced various degrees of fractional crystallization, but they keep geochemical information of the source mantle. Tertiary volcanic rocks from various parts of Central and Northeast Japan were studied. A non-peridotite mantle source is suggested from the low-Ni basalt of the Hokuriku Province, degree of melting of the source mantle and its chemical characteristics were determined from the primitive basalt of the northeastern Yamagata Prefecture, and the similarity and difference of the source mantle were discussed by comparing rhyolites from Northeast Japan and continental rift zone.
