So the age data mostly from porphyroid muscovite record the action time of the Tan-Lu fault zone. And 190 Ma,the ~(40)Ar/~(39)Ar age of muscovite, is the cooling age close to the deformation age of the ductile shear zone.

• 该温度值大于40Ar/39Ar法中白云母的封闭温度,从而由主要以残斑形式存在的白云母获得的年龄值记录了郯庐断裂带的活动时间,190Ma左右的白云母年龄值为接近于韧性剪切带变形年龄的冷却年龄。
