英文摘要	In the last two decades, EBSD (Electron Backscattered Diffraction)has been widely used as a routine approach in ductile fabric analyses, focusing on flow kinematics and rheology of ductile deformation. It is predominantly applied to determining the shear.sense of the bulk flow, evaluating strain strength, and assessing deformation temperature via analyzing Crystallographic Preferred Orientation (CPO)and deformation mechanisms of recrystallized minerals. Theoretically, EBDS retains the potential to recover the crystal-axis orientation of all minerals. However, dynamically recrystallized quartz grains, particularly, quartz ribbons are recommended for EBDS analysis due to the complexities of natural deformation. Conventionally, quartz c-axis obliquity is used as a reliable and independent shear-sense indicator, while the c.axis opening angle and recrystallization mechanisms of quartz (i. e., bulging, subgrain rotation, and grain boundary migration)have been treated as deformation thermometers. However, recent studies on naturally deformed rocks and general-shear experiments indicate that cautions must be exercised when using EBSD results to extract flow kinematics and multi-criteria are suggested for a proper interpretation of flow kinematics in ductile shear zones. Similarly, limited to our understanding of the process of natural deformation, particularly the coupling between metamorphism and ductile deformation, crystal fabric-based deformation thermometers have their own caveats and limitations that EBSD-derived thermal data, the quartz c-axis opening-angles, may also be subject to multiple interpretations although it was originally proposed as an independent deformation thermometer (Kruhl, 1998).
