| Research Abstract |
I surveyed some geologically ancient complexes forming the frame of the Japanese Islands in order to clarify the origin, and got many rock samples. Particularly, I worked much on the mafic-ultramafic complex on the Yamaga district in central Kyushu for this research. For the rock samples, I observed petrography and then analyzed major and trace element compositions for considering about source materials. As a result, it was found that the mafic-ultramafic rocks of the area were composed mainly from cumulate and cumulous igneous rocks based on the characteristic in the major element compositions, and basaltic rocks accompanies it; it became clear to, so to speak, have a characteristic of the lower crust.
