摘要
郯庐断裂带南段多发育一套走向为 NNE 方向的韧性剪切带,糜棱岩就产于其中,这里选取三条典型的韧性剪切带作为研究对象,对其中的糜棱岩及其围岩的矿物成分、结构构造、超微构造特征等进行了详细的研究,并对其糜棱岩的成岩条件和机理进行了探讨。
In the south section of Tangcheng-Lujiang fault a series of ductile shear zones have been developed,in which mylonitcs exist.The mineral composition,texture,structure and ultramicro-struc- ture of mylonites and their surrounding rocks from three typical ductile shear zones are studied compre- hensively in the paper.The diagenesis conditions and forming mechanism of mylonites are also dis- cussed.
