| 摘 要： | 根据川东平行岭谷区的展布形态在卫星像片上所反映的影像特征──向斜扬起端呈三角形尖角翘起，背斜倾没端呈圆润的形迹逐渐隐没于地下的现象，从而判定薄皮构造的模式实际上就是一般的箱形褶曲。并指出薄皮构造中的三种褶曲形态呈上下叠置的关系。在外营力的剥蚀与破坏影响下，薄皮构造受到程度不同的剥蚀破坏而呈现出不同的褶曲形态。

| Abstract: | Image information of parallel ridge-and-valley topography in east Sichuan shows that rising ends of synclines rise as a triangle, while plunging crowns of anticlines plunge as a smooth feature.From the image information it is decided that structural pattern of the thin-skinned structure, in fact, is a box fold. Moreover, three folded forms in the box folds are superposed. By the action of exogenetic force, the thin-skinned structure was subjected to denudation to varying degree, appearing as different folded forms. |
