中文摘要: 叠加褶皱作为地壳构造变形中一种常见的地质现象,对于确定多期变形和构造运动期次,探讨构造演化历史以及内外生矿床的空间分布、形成与变形特征均有重要研究意义。在回顾叠加褶皱研究历史与近年来取得的主要进展基础上,系统地总结了叠加褶皱几何学与运动学特征,指出叠加褶皱主要有纵弯褶皱作用、横弯褶皱作用及剪切褶皱作用3种成因机制。在此基础上,选取典型的叠加褶皱,剖析了其构造样式及形成机制,并探讨了叠加褶皱研究的难点与可行研究方法。
Abstract:Superposed fold, representing one of the most significant structures, is predominately derived from multistage crustal shortening, documenting a multiphase tectonic evolution history in a certain region. In order to deepen the understanding of the superposed fold, this paper gives an overview of the previous studies for superposed fold, and mainly focused on the structural style and formation mechanism. Here we suggest a superposed fold is dominantly originated from buckling folding, bending folding or shear folding, as reveled by an amount of field observation, physical and numerical simulation; then we give two case studies on the superposed fold. Additionally this paper summarizes a number of issues and probable methods on superposed fold analyzing.
