对遭受脆性变形(尤其是断裂作用)的岩层进行古构造应力恢复是进行地壳构造变形历史和动力学研究的重要手段之一。对带有擦痕线理的断层进行大量观测,不仅便于精确描述断层几何学,而且还可使地球上部脆性地壳的构造模式与应力状态相关联,从而再现构造应力场在时空上的演化特征。对脆性构造研究中的断层滑动分析与古应力恢复这一方法的研究历史与现状、原理假设、数学方法以及如何把反演结果与野外地质认识相结合进行构造变形期次的研究进行了介绍和评述,并指出这种方法不仅有利于认识盆地与造山带在构造应力场上的同一性,而且有利于从动力学上去探讨盆山之间的关系,在目前盆山耦合的构造研究中有其自身的优越性。

Palaeostress reconstruction of brittle deformed rock is one important way of research into the crust structural deformation history and geodynamics. Lots of measurements of faults with slickenside lineations enable us not only to accurately describe the geometry of fault systems, but also to provide an opportunity to investigate how such structural patterns in the upper brittle crust are related to the state of stress during tectonic events. Also, it helps us reconstruct the stress field and its evolution characterization in space. The paper just presents a brief introduction and some comments about the principle and hypothesis, mathematical method of fault-slip analysis and palaeostress reconstruction, and discusses how to relate the interpretation of the inversion results to the geological observations in the field. The authors believe the most important is the combination between accurate and lots of observations in fields and calculated results. At the same time, it points out that this method is useful not only for understanding the consistency of tectonic paleostress field between basin and orogen, but also for exploring the relation between basin and orogen geodynamically. Faultslip analysis has a priority in tectonic analysis of basin and mountain coupling exactly.
