| 摘 要： | 大型变形构造带是地球表层重要的构造现象,它们记载了地壳的构造变形（走滑错移、逆冲叠覆和伸展滑移）过程及其动力学机制。本文根据大型变形构造定义及其分类原则,将甘肃省大型变形构造划分为3大类10种类型,初步厘定出大型变形构造带23个,简要叙述了主要大型变形构造规模、产状、构造层次、物质组成、变形期次等基本特征,探讨了大型变形构造与蛇绿构造混杂岩带的关系,从全省北山造山带、祁连造山带、西秦岭造山带和鄂尔多斯盆地“三带一盆”的构造格局出发,探讨大型变形构造形成、演化历史。

| Abstract: | The large scale deformation structure belt is an important geological phenomenon on earth surface, which recorded process and dynamic mechanics of structural deformation. According to definition and classification principles of deformation structure, the large scale deformation structures in Gansu Province are grouped into 3 categories including 10 types. The paper described briefly scale, occurrence, hierarchy, material composition, deformation periods and phases of those structures, discussed the relation between large scale deformation structures and the ophiolite tectonic mélange belts, also explained the evolution history of those structures from the view of 3 Belt and 1 Basin, i.e. Beishan, Qilian, West Qinling orogenic belt, Ordos Basin. |
