四国西部における御荷鉾緑色岩類と秩父帯北縁部の地質構造

Geological structures of the Mikabu greenstones and the northern margin of the Chichibu Terrain in West Shikoku, are reexamined. The Mikabu greenstones are distributed from the south of Yawatahama to Mt. Tomisu-yama continuously. The Mikabu greenstones with red cherts are thrust over the strata of the northernmost Chichibu Terrain along the Kitatada thrust. The strata of the northernmost Chichibu Terrain strike E-W and dip toward north fundamentally. The Tosaka window and Kurakawa syncline of Matsuoka et al. (1998) do not occur in the Chichibu Terrain of West Shikoku.
