抄録

Hydrous mineral inclusions in chromian spinel were commonly found in chromitite from the Yanomine complex, one of the dunite-harzburgite complexes in the Sangun zone of the central Chugoku district, southwest Japan. Hydrous minerals are Na-phlogopite and pargasite, both of which are relatively high in Ti. Similar inclusions were also found in spinel in dunite from the Yufune complex and in troctolite from the Ashidachi complex. Chromitite pods which are relatively large-scale from the Tari-Misaka complex have no hydrous mineral inclusions in chromian spinel. Existence of hydrous mineral only as inclusions in chromian spinel may indicate a melt which is enriched with incompatible elements played an important role during precipitation of chromian soinel in the Yanomine comolex.
