Description
The late Paleozoic Ebi Tectonic Zone, newly proposed, is a suture zone developed outer margin of the Hida Belしwhich is now bounded by the“Sangun Metamorphic Terrane”of the Chugoku region. It is a zone, consiting of a mylonite granitic rocks and melanges from north to south. The Ebi Granite gradually changes into the mylonite granitic rocks in the Ebi Tectonic Zone, and mylonites vary in granitic rocks, greenstones, and andesites. The melanges embedded clasts of andesites, granitic rocks in a siltstone and tuffaceous sandstone matrix.
The Ebi Tectnic Zone thrust ove}the pelitic schists of the“Sangun Metamorphic Terrane”.
