| 摘 要： | 安徽省青阳地区早古生代地层普遍发生了较强烈的韧性变形，主要变形形迹有：滑脱断层、顺层劈理、小型韧性剪切带、流变褶皱、石香肠等，显微构造分析也显示岩石的韧性变形、强烈的构造置换作用．岩石的构造变形达中－下部构造层次上部，其形成机制为重力滑覆成因．

| Abstract: | Ductile deformation usually occurs in the early Palaeozoic strata in the Qingyang area of Anhui, such as: glide fault, cleavage, small ductile shear, rheomorphic fold and buding, etc. Ductile deformation and strong transposition of structure were disclosed by microtectonic analysis. The tectonic deformation reaches to the upper part of the midlower tectonic level and its forming mechanism is gravitational gliding. |
