中文摘要：
韧性断裂构造形成时限的研究自提出以来得到了一定程度的发展，目前的研究方法主要有反应速率法、扩散速率法和应变速率法3种。最近的研究表明，对同一韧性剪切带，应变速率法和有限应变测量法所得构造形成时限均以10^4a为数量级，并且均随着糜棱岩化程度的增加而逐渐减小；不同韧性剪切带的构造形成时限也均以10^4a为数量级，其差异是由构造动力学条件不同引起的。利用应变速率法所得构造形成时限具有较好的内部一致性，这在一定程度上表明利用应变速率法测定构造形成时限是可行的。在超薄片厚度、不活动组份、糜棱岩化温度和最适用古应力计等的确定上目前仍存在争议。文中还对体积因子和糜棱岩化程度等对求算构造形成时限的影响以及构造形成时限的发展方向进行了深入讨论。构造形成时限研究整体来说仍处于探索阶段，目前只能达到半定量的程度，有待进一步的深入细致的工作，同时也有待于显微构造地质学、构造岩石学等相关学科的进一步发展。
英文摘要：
Since the concept of deformation duration of ductile faults was proposed, certain of progress were made. There were three approaches to the issue： reaction rate method, diffusion rate method and strain rate method. The recent work indicated that the durations achieved by strain rate method and finite strain measurement method were both of the order of 104 years, and they decreased gradually with the mylonitization in the same ductile shear zone. As to the different shear zones, although the durations were also of the same order, there were differences among them and they were caused by the conditions of tectonic dynamics. The durations given by strain rate method had a good consistence repeatability, and indicated the feasibility of the approach. There were still some arguments in the determination about thickness of thin-section, immobile components, deformation temperature and the most suitable paleopiezometer. This article presented a deep discussion on the influences of volumetric factor and mylonitization degrees on deformation duration, and the perspective on the study. The relevant study at present is still in the period of exploring, and is only confined to half-quantitative analysis. It requires deeper and more delicate research, and development in microstructural geology and tectonitic petrology.
