• The area along the so-called Median tectonic line between Sakuma Dam and Ikeba, mainly consists of an older complex including the Kashio mylonitic rocks, the Ryoke metamorphic rocks and the Ryoke granitic rocks, together with the Neogene Tertiary rocks belonging to the Shidara group and the Shidara volcanic rocks. The older complex shows a zonal structure trending pararell to the so-called Median tectonic line, while the structure of the Neogene Tertiary rocks is discordant with this zonal structure. The three systems of faults and joints, namely A system (NE-SW), B system (N-S) and B' system (NW-SE), predominantly develop in this area. Of these three systems, A is older and strikes pararell to the so-called Median tectonic line, while B and B' are younger, acrossing the so-called Median tectonic line. The B and B' faults are noteworthy in suggesting lateral movement, right or left, rather than vertical movement. There is almost no doubt that B and B' systems are closely related in genesis to A.
