The anatomy of small - scale to meso - scale deformational structures have resulted in the reconstruction of the structural framework of the yanbian group . the statistical analyses of the fold hinge and cleavages developed in the yanbian group suggest the trend of the first stage penetrating structures of the yanbian group is een - wws . 2 基于对盐边群中、小尺度变形构造进行构造解析，建立了区域构造格架，通过对褶皱枢纽和劈理的分析，提出盐边群第一期透入性变形构造的走向为北东东?南西西向。
