Kouyama gabbroic body, Susa area, Hagi city, Yamaguchi Prefecture, Japan, were mainly consist with diorite and gabbro. Modal analysis for opaque minerals were performed by microscope. Magnetite and ilmenite including their rocks were studied by ore microscope and electron probe microanalyser. Vanadium contents of magnetite in diorite are ranging from 0.43 to 10.75 wt % V2O3 and average is 1.82 wt % for 220 analytical data. Their content in gabbro are in the range from 0.59 to 3.13 wt and average is 1.93 wt % for 500 analysis. Ilmenite associating with magnetite contains less than 1.13 wt % V2O3 but includes with some amounts of MnO from 0.28 to 5.06 wt% for diorite and 0.12 to 6.20 wt % for gabbro.
