Two kinds of magma are probably derived from the initial magma in the Himekami pluton. The content of magnesium is the major difference between the two magmas. They produce the present four rock groups through two different processes in which the rat

In the Hanaoka mining area of the “Green Tuff” region, the Miocene submarine lavas and pyroclastic rocks with basaltic to andesitic compositions were recrystallized at low temperatures to form various secondary minerals. The upper metabasites are

Chemical compositions of biotites and hornblendes in metamorphic rocks around Lutzow-Holmbukta show that these minerals have the characteristics of granulite facies ones. Some low-Ti biotites and hornblendes may be due to low TiO_2 content of host ro

K-Ar ages were determined on some metamorphic rocks from the Sanbagawa terrain. The ages obtained are mostly of Middle and Late Cretaceous (110-67 m. y.). This range may not indicate the age of the main stage of metamorphism, but may represent the ag

The Nishidohira cortlandtitic mass of probable Late Mesozoic age in the southern Abukuma Mountains has been characterized on the basis of field evidence, microscopic observations and chemical analyses of rocks and minerals. Though the mass is small,
