| Research Abstract |
The Sambagawa high P/T metamorphic zone, central Shikoku, is reginally mapped. Mapping is based on dividing metamorphic mineral zones into the Oboke psammitic schist, main chrolite, chlorite L tectonite, garnet, albite-biotite, and oligoclase-biotite zones. Additionary, characteristic lithologies of psammitic schist, calcareous schist, piemontite siliceous schist, mafic schist, amphibolite, eclogite, metamorphosed ultramafic rocksare are also mapped. Exhumation was carried out by wedge extrusion associated with detachment faulting, followed by out-of-sequence thrusting associated with duplexiing, and then uplight folding. The Median Tectonic Line should be a root of the Sambagawa metamorphic rocks. Eclogite might have been derived from the Mikabu ophiolite.
