复合褶皱是多次运动和多变形地区非常普遍的构造现象,特别在古老变质岩区和造山地带,分布更为广泛,表现形式也更加复杂。组成这些地带的在不同的构造运动或者不同的变形阶段中所生成的褶皱系统,不论其延伸方位或是褶皱型式都经常表现出某种程度的差异性。指示具有复合关系可能性的构造迹象是多种多样的,诸如不同方位不同类别的劈理面的交割,某种劈理面的规律性的弯转,各种线理的再定向和再变形,以及褶皱 Composite folds are the most common tectonic phenomena in many areas of motion and deformation, especially in the ancient metamorphic areas and orogenic belts. They are more widely distributed and more complicated in form. The fold systems that form these zones in different tectonic movements or different deformation stages often exhibit some degree of variability, regardless of their extension orientation or fold patterns. Construction indications that indicate the likelihood of a compound relationship are numerous and varied, such as the delivery of cleavage planes of different orientations, the regular turning of some cleavage planes, the reorientation and reformation of various lines, And folds
