摘要
低角度正断层的形成机制是大陆伸展构造研究中的热点问题之一，关于其形成机制及其与其几何学的关系争论很大。到目前为止，人们根据北美西部及其它地区的变质核杂岩构造研究提出了许多有关低角度正断层的形成模式。本文重点介绍并评述了比较流行的三种模式：滚动枢纽模式、低角度正断层的岩浆驱动机制模式、应力导层与低角度正断层的发育模式。
The origin of low-angle normal faults is one of the important questions in the study of continental extensional tectonics. There are a lot of arguments about the relationship between the origin of low-angle normal faults and their geometry.So far,a number of models have been proposed for the origin of low-angle normal faults on the basis of the metamorphic core complexes in the west of North America and other regions.In this paper,we introduce and review three the popular models: the rolling-hinge model,trigering mechanism of magmatism model and the stress guide model.
