Abstract
The granitic rocks and their mylonitic facies with small amount of the high-grade metamorphic rocks are distributed in fault contact with the surrounding Miocene sedimentary rocks in the Hiki Hills at the NE marginal area of the Kanto Mountains. The granitic rocks are mostly medium-grained gneisses tonalite and granodiorite which are correlative to the Hiji tonalite in the Chubu district. The metamorphic rocks comprise andalusite gneiss and sillimanite gneiss. Suggests that the large-scale bending of the Median Tectonic Line at the Fossa Magna area occurred after the stage of mylonitization of the Ryoke granitic rocks. -from English summary
