摘要
褶皱是韧性剪切带内普遍发育的构造变形,是研究韧性剪切带乃至造山带构造作用的桥梁,但是对于剪切带中存在的这类褶皱国内尚无统一命名,本文根据剪切带内褶皱的最新研究成果,引进了"韧性剪切带相关褶皱"的概念。目前,国内外学者对韧性剪切带相关褶皱(尤其是鞘褶皱)的研究多集中在运动学和动力学上。本文介绍了韧性剪切带相关褶皱的类型及其研究方法,为客观理解韧性剪切带相关褶皱的形成机制提供了新思路和方法,进而为恢复陆内造山作用过程提供了客观的约束条件。
Fold is common structure which developed in ductile shear zones, it＇s a bridge to the exploration of ductile shear zones and orogenic belt structure. However, here is no unified naming for this kind of fold exist in the shear zone both at home and abroad. Based on the latest research results of fold in shear zones, the concept of ＂fold related to ductile shear zones＂ is introduced in this paper. Recently, the study of fold related to ductile shear zone（especially sheath fold） most focused on the kinematics and dynamics. This paper introduces the fold related to ductile shear zone type and its research methods, provides a new thought and method to objectively understand the formation mechanism of fold related to ductile shear zone, and then provides objective constraints to resuming the process of intracontinental orogeny.
