抄録

In the Besshi district of the Sambagawa metamophic belt,basic schist layers o㏄ur crossing the middle portions of the Seba valley,there are two texture types of prograde eclogites.One is fomed by contact metamorphism of emplacement of high grade tectonic-block. They occur in the area that is only a few 1O m from the tectonic-block.They are randomly oriented and have coarse-grained omphasite porphyroblastes. The other type has fine-grained omphasites forming schistosity and lineation. Some eclogites retain eclogite facies mineralgg,and they occur in wide area of the Sebadani area. Therefore there is a possibility that the Sambagawa schist in this area were reached to the eclogite facies P-T conditions.
