Abstract
The basic rocks is included in the trondhjemitic migmatite or in the tonalitic migmatite, at the midstream of the river Horoman, Hidaka province. In this paper, some microscopical relations between the component minerals of the migmatite and of the basic xenolith are described. The auther concludes that the basic xenolith is the origin from the biotite rich hornfelsic rock which is basified before the xenolith is included in the migmatite.
