Geologists always face lots of difficulties in structure analysis of concealed me-tamorphic rocks series. The most difficulties are (1) to orientate fabrics in drill hole and (2) to establish the key bed. To overcome these difficulties is not so easy as in the exposed area, but it should be the necessary first step in any attempt to determine the structural pattern, and is thus the means in the specialized studies in such an area.We proposed, in this paper, a method which generalized much of ,the previous methods making it more appropriate to concealed areas of metamorphic rocks. It is pointed out how to determine and distinguish the orientation of S-surface of multi-phases of deformation and how to establish the key bed of concealed metamorphic rocks by using the data from drill cores and finally how to construct the structural profiles of the selected area as an example.
