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.

- 該溫度值大于40Ar/39Ar法中白云母的封閉溫度,從而由主要以殘斑形式存在的白云母獲得的年齡值記錄了郯廬斷裂帶的活動(dòng)時(shí)間,190Ma左右的白云母年齡值為接近于韌性剪切帶變形年齡的冷卻年齡。
