摘　　要：简要概述了绿辉石的晶体结构、反相畴、显微构造及其变形机制等方面的研究现状与进展。结合大别山榴辉岩中绿辉石的最新研究成果，着重讨论了其构造物理学研究意义，认为绿辉石晶体结构的有序化不仅是温度和化学成分的函数，而且是晶内应变程度的函数。In this paper,a systematic review about the recent researching achievements of omphacites in their crystal textures and antiphase domains as well as microstructures and their deformation mechanism is given.Then the paper tentatively discusses the structural physical significances of the naturally deformed omphacites based on the study of them from Dabieshan eclogites.It is suggested that the ordering processes of omphacites are not only a function of temperature and chemical composition,but also a function of intracrystalline deformation.
