This paper deals with and summarizes the research and importance of ductile shear zones and presents the future direction and aim for the research of the ductile shear zones around the world. Four aspects of studies of the ductile shear zones have been proposed in this paper as follows:(1) The stress environment including the mineral assemblages, deformation, stress-shearing parameters;(2) The major element sequence and activation under condition of stress;(3) The variations of trace elements and REE, their transportation distributions under strong natural deformation as well as variations of mineral crystal parameters, which can also control the element changes during the ductile deformation;(4) The relationship between element migrations, activation and stress, which will present the new evidences for the studies of dynamic diagenesis and mineralization as well as the studies of evolution of ductile shear zones developed in middle and low levels.(5) The analysis of elements and isotopes in mylonites on the micro-scale are crucial for the understanding of component migrations during the mylonization.

对韧性剪切带及其变形岩石的研究现状和研究意义进行系统的综述，提出了未来韧性剪切带及其糜棱岩的研究方向和目标：①系统研究糜棱岩中主要造岩矿物组合及其变形特征，计算剪切变形岩石的应力－应变参数，搞清韧性剪切带所处的应力应变环境；②系统研究韧性剪切带岩石在天然分强剪切应力作用条件下常量元素迁移机制及活化转移的应力排序问题；③系统研究剪切变形作用过程中岩石化学组成的微量和稀土元素变化，讨论强变形条件下岩石中微量元素活化和迁移规律，深入探讨微量元素迁移的动力控制，包括稀土元素配分变化的应力制约以及应变矿物晶格化学变化行为及其对其寄主的变形岩石元素在应变过程中迁移变化的制约和影响；④从理论上探讨天然强剪切应变条件下岩石中组分活化、转移与应力的因果联系，为深入探讨韧性剪切带动力成岩作用提供理论的科学依据，为探讨中、下地壳中韧性剪切带的形成和演化提供科学依据，同时为韧性剪切变形作用条件下成岩、成矿地球化学作用提供理论和实验依据；⑤现代分析技术如激光同位素原位分析以及激光ICP-MASS分析技术对研究变形域内的岩石的元素和同位素的活化迁移规律，对深刻揭示糜棱岩化过程中的元素活化迁移机制提供更高质量的地球化学证据具有重要的作用。
