Fig. 2From: Clockwise rotation of SW Japan and timing of Izanagi–Pacific ridge subduction revealed by arc migrationDistribution of geological terranes in NE and SW Japan (data from Geological Survey of Japan, AIST 2022). NE and SW Japan are divided by the Tanakura Tectonic Line (TTL). In this study, we interpret the Median Tectonic Line (MTL) as a major fault that defines the northern limit of occurrence of geologic terranes in the outer zone (Sanbagawa, Chichibu, and Shimanto belts) and is essentially identical to the Usuki–Yatsushiro Tectonic Line (UYTL)Back to article page
