褶皱构造是地壳上广为发育的构造现象,在实际工作中,对它的分析和研究如同研究断裂构造一样,对阐明区域构造发育和形变的历史有着十分重要的意义。 大量的实际资料证明,在自然界层状地质体中所表现出来的褶皱形迹,广为多见的是属于弯滑褶皱类型,亦即岩层面是褶皱变形的滑移面,层面各点均围绕褶皱的枢纽作旋转运动的褶皱类型。这种弯滑褶皱不仅有侧向挤压应力作用形成的,而且也有因妞动
The fold structure is a widely developed tectonic phenomenon in the crust. In practice, its analysis and research, like the study of fault structure, is of great significance for clarifying the history of regional structural development and deformation. A large number of actual data prove that the folds displayed in the layered geological body in nature are widely seen as belonging to the type of curved folds, that is, the surface of the rock is the slip surface of the folds and the points of the layers are all around the folds The hub for the rotational movement of the fold type. This bending and creasing folds not only the role of lateral compression stress formed, but also because of Niu move
