| 摘 要： | 早期褶皱的迁移机制和迁移型叠加类型的发现扩大了对广义纵弯褶皱叠加机制和类型的认识。广义叠加机制有多种，其中包括迁移和位移，褶皱变缓和展平，岩层变陡和变缓等。广义叠加类型中除基本类型外还有限制型、展平残留型、叠加挠曲、共轴重褶等。本文将用几个地质实例予以说明。此外还将讨论叠加褶皱层应变和小构造的多成因和应用问题，其中包括斜纵弯应变和褶皱变缓展平引起的应变和小构造。

| Abstract: | The shift mechanism of early fold and the shifted superposed fold exploit the knowlege on generalized superposed mechanisms and types.The shifting and displacement,the opening and unfolding fold,the steepen and gentlen layer are included in the generalized superposed mechanisms.The restricted fold,the unfolded remaining fold,the superposed monoclinal flexures and the coaxial refolded type are in the generalized types.To explain the problems above some geological examples are introduced.The strain and small scale structures in fold layer specially caused by the oblique buckling,opening and unfolding are discussed. |
