Descriptions
Present author recently found gneissic xenoliths in dacite gravels of Motodani, westward valley of Mt.Daisen.
From the results of petrological studies, these gneissic rocks are judged to be the rocks of Hida-Oki metamorphic belt.
It is important problem to know not only the basement rocks of Mt.Daisen but also south extremity of Hida-Oki metamorphic belt.
The discovery of gneissic xenoliths from Mt.Daisen sugests the existence of similar materials to those gneissic xenolithsin considerable amounts under Mt.Daisen.
