摘要： 对郯庐断裂带南段两条典型的中深层次的声望生剪切带中的糜棱岩的系统研究，揭示了韧性剪切变莆作用对岩石化学级份迁移活化的制约和影响，在对活动组分迁移得失的模拟计算的基础，建立岩石组分迁移变化的变质反应化学方程式，综合讨论了流体在糜凌岩化过程中所起的重要作用。

Abstract: The paper focuses on the systematic study of two typical ductile shear zones in median- deep levels from the southern part of Tancheng-Lujiang fault belt. The influence and restrain on the chemical component migration and activation in the rocks by ductile deformation have been revealed. On the basis of simulant calculation of the migration of active component in the rocks, the authors have established the chemical reaction equations of different metamorphic rock pairs，The paper also discusses the important role played by fluids in the mylonitization.
