浅变质碎屑岩中韧性剪切带的变形特征不同于长英质岩石中的韧性剪切带。以江西大背坞地区为例，阐述了在浅变质碎屑岩中鉴别韧性剪切带的标志，提出这种变形的构造岩的分类方案，同时对大背坞地区韧性剪切带进行应变测量和剪切位移估算，最后在岩石组构特征和综合分析基础上指出这种韧性变形机制是粒间滑动和粒内变形，其形成深度５～８ｋｍ、温度２５０～３５０℃、压力０１０～０２０ＧＰａ，是一种发育在地壳浅层次的低温低压条件下的韧性变形，其变形变质作用相当于低绿片岩相。
The deformation characteristics of the ductile shear zone in the shallow metamorphic clastic rocks are different from the ductile shear zones in the felsic rocks. Taking the Daduwu area in Jiangxi Province as an example, this paper expounds the identification of ductile shear zones in shallow metamorphic clastic rocks and proposes a classification scheme for this deformed tectonic rocks. At the same time, strain measurements of ductile shear zones And shear displacement estimation. Finally, based on the rock structure characteristics and comprehensive analysis, it is pointed out that the ductile deformation mechanism is intergranular sliding and intragranular deformation. The formation depth is 5 ~ 8km, the temperature is 250 ~ 350 ℃, the pressure is 010 ~ 020GPa, is a kind of ductile deformation developed at the shallow crust of the earth’s crust under low temperature and low pressure, and its metamorphism and metamorphism is equivalent to the low-greenschist facies.
