Abstract

Geological structures of the Mikabu greenstones and Northern Chichibu Terrain were studied in the Miune-Tsurugisan area, Middle East Shikoku. The Mikabu greenstones and phyllite with schistose sandstone and chert of the Northern Chichibu Terrain are folded by the Tanimichi antiform, which occurs from north of Tanimichi, to north of Shiragayama with ENE-WSW trending. Thick basaltic volcanic rocks of the Northern Chichibu Terrain, occurring in the south wing of the antiform, occupy the same structural horizon as the Mikabu greenstones. Therefore, the volcanic rocks are possibly correlative with the Mikabu greenstones. The Tanimichi antiform is displaced by the left-lateral strike-slip Kaminirogawa fault, and probably extends eastward to the Kisawa area in East Shikoku.
