The study area is mainly composed of metasedimentary rocks which are included in Ogchon, Choson and Pyongan Groups. Because of thrust faults which are developed in this area, a coal bearing formation is repeatedly distributed two times, and Choson Group is thrusted over Pyongan Group. Deformation in this area was taken place in a series of three phases ((D₁, D₂ and D₃) ; D₁ was most intense whereas D₃ was weakest. Thrust faults developed in the upper curst during D₂ produced cataclastic rocks and fault breccia, truncating regional slaty cleavage and earlier folds which were formed during D₁ stage. The quartz microstructures of metapsammitic rocks in Choson and Pyongan Groups suggest that dislocation creep mechanism predominated early in fabric development, afterwards deformation mechanism was transfered to pressure solution which intensified the earlier fabrics. According to strain analysis using quartz grains and quartz aggregate grains, the strain magnitude(Es) of Pyongan Group represents larger values than that of Choson Group due to the contrast of constituent minerals, the size of original quartz grains and matrix content. Apparent flattening type in strain pattern appears in the whole area. It is suggested that the relationship between Ogchon Group and Choson Group may be thrust contact.

The study area is mainly composed of metasedimentary rocks which are included in Okch'o˘n, choso˘n and P'yongan Group. Because of thrust faults which are developed in this area, coal bearing formation is repeatedly distributed two times, and these put Choso˘n Group on P'young Group. Deformation in this area was taken place through a series of three phases (D_l, D_2, _3), D_1 was most intense, weakened D_2, D_3 in order. Thrust faults developed in the upper crust during D_2 produced cataclastic rocks and fault breccia, truncated regional salty cleavage and earlier folds which were formed during D_l stage. The microstructures of metapsammitic rocks suggest that dislocation creep predominated early in fabric development, afterwards deformation mechanism was changed to pressure solution which intensified the earlier fabrics. According to strain analysis using quartz grains and quartz aggregate grains strain magnitude (Es) of P'yongan Group represents larger values than that of Choso˘n Group, and that of P'youngan Group increase gradually toward left margin. Apparent flattening type in strain pattern appears in the whole area. It is suggested that contact between Okch'o˘n Group and Choso˘n Group is thrust fault.
