箱状褶曲是地壳上較普遍的一种褶曲形态,闡明其形成机制在理論上和实践上都有一定的意义。箱状褶曲有不同的成因类型。从形成箱状褶曲的力的作用方式考虑,可把它們分为由基底断块垂直运动造成的(横弯曲型的)和側向挤压造成的(纵弯曲型的)两类。前一类型在文献中已有过較多的討論[4,7,9,10]。它們以受垂直力作用为主导,在剖面中上下岩层褶曲形态协調(即使有不协調現象也仅出現于肩部),所以可把它們叫做协調型 Box-fold is a common crust on the earth’s crust, clarifying its formation mechanism in theory and in practice have some significance. Box folds have different genetic types. In terms of the mode of action of the force forming the box-like folds, they can be divided into two categories (vertical bending type) and (lateral bending type) caused by the vertical movement of the base block. The former type has been discussed more in the literature [4,7,9,10]. They are dominated by the action of vertical forces, and the coordination of the fold formation of the upper and lower strata in the profile (even if there is an uncoordinated appearance of the shoulders), they can be called coordinated
