抄録
Small granitic bodies of the Mitaki igneous rocks of the Kurosegawa Terrain occur in the area to the north of Mt Mitaki, in the Onogahara-Torigatayama Area, West Shikoku. These granitic bodies measure 40-60 m wide and 350-600 m long. They are metamorphosed under pumpellyite-actinolite facies conditions to form pumpellyite, actinolite, chlorite and albite. Phyllites, calcareous sandstones and greenstones with actinolite occur around the granites. They possibly constitute the Permian accretionary complex. The Permian accretionary complex underlies the Jurassic accretionary complex by fault. Amphiboles of the greenstones, which are thought to be the Younger Ino metamorphic complex of the Kurosegawa Terrain, are glaucophane or ferroglaucophane, and coexist with pumpellyite. These greenstones are correlated with those of the Kurosegawa Terrain in Central Shikoku. On the other hand, amphiboles of the Permian accretionary complex near the Torigatayama-Onogahara limestone body are actinolite-ferroactinolite or winchite-ferrowinchite, showing lower-grade metamorphism than the Ino Metamorphic Complex.
