摘　　要：叠加褶皱的研究是以叠加机制和叠加类型为基础的。从变质岩构造研究中形成的叠加褶皱理论是以剪切褶皱为基础，而沉积岩的纵弯褶皱叠加机制和类型均与之不同。国外有学者分别指出再褶皱时的斜纵弯褶皱机制和早期褶皱枢纽的迁移机制以及四种基本叠加类型。我国有人论述了早期褶皱的枢纽、拐线的迁移是正纵弯再褶皱的一种机制，依此提出了正纵弯叠加褶皱的三种基本类型。本文对这些成果的主要认识和依据予以介绍。The research on superposed folds is based on the understanding of the mechanism and the types of superposed buckling.The theory of superposed folding is from the research on structures in metamorphic regions which are different form that in sedimemtary rocks.Some foreign geologists put forward the superposed mechanism of oblique flow buckle fold and the hinge migration of early fold during refloding and four standard modes of superposed buckling.Some domestic workers expound that the hinge and inflexions shifting of early fold as a mechanism of superposed normal buckle fold and three basic types of superposed normal buckle fold.This paper presents these achievements and the contrast.
