Lithology and Thickness
The third group is characterized by highly foliated and folded pelitic schist with minor siliceous, psammitic and basic lithologies (type III, ie. Pankehoronai unit of Sakakibara & Ota 1994). It is also characterized by a pumpellyite-actinolite facies metamorphism with calcite instead of aragonite, and actinolite instead of glaucophane, indicating a higher thermal gradient than that of the Iwashimizu Complex.
Lithology Pattern:
Gneiss
Relationships and Distribution
