轴面劈理-
第二期形成北东向中常褶皱及轴面折劈理；
The second by north east-trend neutral folds and axial crenulation cleavage ;

第二世代为与第一世代近共轴的具轴面褶劈理的近水平直立片理褶皱；
The second one , nearly coaxial with the first one , is composed of subhorizontal upright schistosity folds with axial crenulation .

晚期褶皱表现为不同时代、不同方向、不同类型的叠加褶皱，轴面近直立，有时伴有轴面劈理。
The later folding is characterized by the superposition of folds of different ages and orientations , nearly-vertical axial-plane and rare cleavages .
