在地质上应用变形椭球的概念研究构造形变已有一段历史了。自Becker(1893)以来,得到越来越多的应用。它的基本观点是,在均匀应变情况下,一个原始的球形物体,在变形后成为椭球体;根据椭球的形态可以确定应变状态。这是研究构造变形的理论基础。因此,一般需要寻找出变形岩石中具有球形或近似球形原始形状的标志物;根据 The use of the concept of deformed ellipsoids in geological studies of structural deformation has been a thing of the past. More and more applications have been available since Becker (1893). Its basic point is that in the case of uniform strain, an original spherical object becomes an ellipsoid after deformation; the strain state can be determined according to the shape of the ellipsoid. This is the theoretical basis for studying structural deformation. Therefore, it is generally necessary to find markers with a spherical or nearly spherical original shape in the deformed rock;
